They were only talking about knurling the guides because it would cost about $65 for the set as opposed to over $200 to replace them. I got another place that I am going to give a shot on Monday.

Cudavert you say this because of the larger combustion chamber? From what I see the heads I have now are 57-64cc while the numbers for the above are 64-71cc.

Do you know what years of 318 heads will work? I found some on ebay that look good, casting number 4027163 from 1984.

Got word from my local machine shop. Heads are shot. Need complete work, new valves, guides and the seats are sunken. So im looking at alternate ideas. Earlier someone said if I went with eddy's I would have to modify my block for the valves to clear. I have since discovered that the cylinders...

I have a 66 Dart 273 convert as my daily driver. It has 40 over flat top pistons with hydraulic lifters (and I assuming hydraulic cam as well). I took my heads (920's) off my small block 273 and the machine shop said they are completely worn and will need new valves, guides need to be rolled...

Victory! Just when I thought I was going to go on a rampage I managed to get it. We unbolted the exhaust manifold and used a crowbar to lift it up about two inches and that was just enough to get my socket wrench under the manifold and onto the final bolt. Both heads are off and will be at the...

Thanks for the input, im gonna try at it today after work. Sorry for the mix up I have stock exhaust manifolds, I wish they were headers. And yes the manifold is unbolted from the head. Today I'll try andlooden the manifold at the collector and see if that helps then jack the engine up like a...

I should have been clearer. I can get all the bolts of the heads except for the bottom center head bolt. The exhaust manifold get in the way. Thats the bolt i gotta get off. Its torqued on tight enough and at a strange angle that i just can't get it off. Hoping for some trick to get that bolt off

I gave a '66 273, with power steering. Block number 2465330, head number 2658920. I managed to get the passenger side off with out too much trouble, but this driver side is causing some troubles. My hands are bloody and bruised so before I started breaking things I thought I would ask ya'll for...

possibly ou812 but I prefer to work locally when I can. Just got the block number, 2465330. I have the passenger side head off but am having some serious trouble with the driver side head. I'm gonna start another thread looking for ideas on best way to remove the head.

I've seen ppl talking about how I would be lucky to have the 920's and my heads say 2658920. Am I really lucky and more importantly why am I lucky???

I did the leak down test on the driver side bank, here are the results. 1- 50% (some leak from exhaust and a decent amount from the dip stick) 3- 65%(leak from exhaust and dip stick) 5- 85% (leak from exhaust and intake) 7- 80% ( leak from exhaust and a little from the dip stick) So overall...

I'm no expert but it doesn't seem rigt to fix just the one cylinder. Because chances are the others could use some work also. Now the tricky part of trying to find a machine shop in Seattle. For those in Seattle, im trying to find a shop in the Ballard area, any suggestions?

heads: 2658920-3 also had 01216 year on block: 11-11-65 vin lp27b62501036 trans: 948-2 With the headers, power steering and brake booster it will be hard to see the block number from above. Hopefully I can find my jack (just moved to a new house) and get that to you all thus weekend

So I took a quick look for the EIN and couldn't find it without hacking the car up. Where can I find it on the block? I was able to find the casting date and it is 11-11-65. Found that on the passenger side.

At this point I am leaning to simpler for now and wait till later to get the power and the 360 going.

any guess on how much to have the heds rebuilt? Im out in Seattle, WA

Thanks for all of the feed back everyone. I think I will try to do a leak down test this weekend to get a better idea of what is actually going on. I will also pull the engine/head numbers this weekend. Then if it points to replacing the heads I will look for a 273 replacement heads (or if I...

JBurch, could you elaborate on the notching of the cylinder, I am not sure that I follow what you are getting at. And C130 Chief, if it will cost be just about the same to rebuild origionals as it would to buy new aluminum heads then I would definately go for the lighter weight heads. I know...

Ok so I have had issues for a while with my 273 and I finally decided to have my mechanic take a look and he quickly found my problem. The number 5 cylinder has little to no pressure. He said he put his thumb over the spark plug hole, cranked the engine and it didnt even push his thumb off the...

Just like this

I did switch the wires and the engine would not start. I was not messing with the timing as I was cranking it. No one here today to help. The timing is currently set to around 15*

I have a Mallory Magnetic Breakerless dist. And a MSD Digital 6a

UPDATE To those that are still subscribed here is the most recent update (and thank you). Reason for thread: Very rough idle When throttle is ever so slightly opened it runs very rough and shakes all over the place Horrible mileage Every once in a while she dies on me when I come to a...

Oh ya and... I have a Mallory Magnetic Breakerless dist. And I checked for vacuum leaks and the intake manifold does have a leak so I will have to fix that soon

UPDATE: I looked into and checked the rotor phasing and it does seem to be late, that is it appeared to be clockwise from where is should be. HOW I CHECKED: Drilled a hole in the plastic dist. cap at the terminal for the #1 cylinder. Fired the car up, hooked up the timing light to the #1...

No, I have serious doubts about it idleing at 3, it doesnt sound like it and i am guessing it is because I have the MSD ignition box
