The holes in the plenum floor are floor jets. Take them out and replace with pipe plugs. I like Allen headed but that's me. Ther pauses can be finicky and there is no tuning parts availability. But I love them.

Honestly I don't want to use either one but for the $ we have something if we need it. since I have 90% of that Edelbrock 600 I'd rather rebuild that than get a hole new education on a thermoquad. I've learned that my education cost money.

It's going to come down to which heads to put money into. I called around yesterday and most machine shops say $40 to resurface but about $65 to 75 to get .040 off. I think I'll clean up the 596 heads and send to be shaved. The 318 heads had been knurled before and absolutely need need guides. where I could probably knurl the 360 guides if I needed to and I'll try lap. I will use the Springs from the 318 and the rockers from 318 because the guy change his oil. The 360 motor you could tell never changed it, just keep adding. Wait a minute now as I write this I start thinking- if I do the knurling and lapping first I'll know if it's worth milling ?

I looked up the knurling tool and not sure what size? When I look up valve stem diameter it seems to very a little ?
65-75 is cheap to cut the heads .040. I wanted to cut the 318 heads but they wanted about 150 here, and that 150 wouldn't fit under my 500.00 dollar umbrella

Think mine were something like $45 each to go .030
Maybe I need to call a few more shops.... but I did call 3.

Each head. 150 for both

I'll order a gasket kit tonight and that will take the total up to $200 so far. Of course along with that gasket kit will come a couple other small little tidbit pieces that'll make up th e 100 order. So if I spend 150 on the head I'm still feeling pretty good. I can definitely reuse to cam, lifters, Rockers and all that stuff. I have that timing chain and I'm going to put the windage tray on so things are coming in to order on paper at any rate.

I'm not familiar with what rotors look like? They both look the same. But I start to think about this the pushrods getting an extra .040 when I mill the head? I plan to try and use the 360 heads and valves with the 318 Springs and Rockers this because they're cleaner and of course the same Cam and lifters.

- First let me say, Jburch is right that .060 is the rule of thumb for "max" milling on small block mopar heads. I don't go the limit, because if it ever needs to be cleaned up .010, I (or the next guy) will have plenty of meat to do that. I have gone .045 before.
- 2nd, when I got my kit, the Fel pro head gaskets that's included are the 8553 head gasket. they are about .050 thick. Your factory tin head gaskets are around .020 compressed. So, the math is easy. You add .030 thickness from the head gaskets, but subtract .040 from the milling, you actually only netting about .010 - 015 thickness. If you went with the Fel pro 1008, you would gain another .012, but spend more money to get the 1008.
- Yes, small block valve springs are interchangeable. HOWEVER, do the 360 heads have rotators???? If so, that changes things a little.....
- Also keep in mind, the 318 heads can be a good option if you need to go that route, but I would certainly add about 25 bucks for porting stones and 8 hours of home porting
- You can also home port the 360 heads. opinion" from a hobbyist, not a professional

Also going to buy intermediate shaft guide, it felt very loose.

How well do head gaskets reuse? I think I still have the ones from the original stroker build.

Only one way to find out. Not that bad swapping them out while the motors still in the car.
Put this in the rtv on the rear of the intake.
Hahahahaha
A budget build is a nickel here and a dime there, and when all done, there really was no budget.
PS , make sure you don't forget the reamer for the bushing. lol

- rotators will only be on the exhaust valves. If the retainers look the same as the intake, then your ok.
- I personally would not reuse head gaskets. There are some really good head gaskets (also expensive) that you can reuse. Unless you have those, I'd put new ones on it.

Oh yeah, it will only be .010 more on the hydraulic lifters. I'm not sure how much play I have with hydraulic lifters.
hydraulic lifters are pretty forgiven.
Chry said that there is .080 clearance,in there Hyd lifters. .010 on each side is un usable so you have .060 to play with.
When my buddy shaved his 360 head down to get some compression, it would not start!!! Had to install a .030 shim under the rocker arm shaft.
Just things you will need to check when you go together.
How do you figure the push rod will only be .010 farther in. You are still shaving .040 off the heads right?
New push rods may break the budget, but rocker arm shims won't.

Going off of 318willrun's calculations in post#226. 40 off with 30 extra in gasket nets 10.

I do have shims that came with my adjustable rockers.

Well I finally finally finally made that order to summit. I've been tired after work and every time I look up parts to finish up the hundred dollar order I keep falling asleep. so I got up this morning and puzzled it together and made $100.90 order LOL. Of course the gasket kit and I also got new water neck because I like a nice new machine surface to work with. Of course the intermediate shaft bushing and sealed power assembly Lube and the bronze freeze plugs.
See I don't get this.
Why pay the extra money to have .040 shaved of the head and then us a thicker head gasket..........If you only want .010 closer piston to head clearance.........why not just use the thin head gasket and have .010 shaved off the head and be done.
.040 was to raise your compression, Right? .010 is not going to make much of a change...........or am i completely lost here........

I'll answer if J par don't mind.....
- Thin head gaskets and cutting the heads .010 will almost cost the same as cutting the heads .040. However, the .040 never goes away . In other words, remove the heads as many times as you want, from project to project, and never have to "re-buy" the more expensive thin gaskets.
- He will always have the option of using, per say, the Fel pro 1008 and gain even more compression..... or the .024 compressed gaskets and gain even more compression. My experience has been he can use the thinner head gaskets with his cut heads and still be ok.

I thought the object was to get it back down to the compression ratio of the original 318 but having better head flow and bigger valves ?
