I was looking to order a set of the head studs for my speed masters as well. On the Summit site, the SMs are still out of stock and it says the substitute for the are the ARP 144-4003 where Turbo's link is for the ARP 144-4005. I am not sure what the difference is but the "003" kit costs a bit...

Does anyone know if the SM aluminum rocker sets fit under stock small block valve covers? I want to use the stock covers.

Cool, not too far away. Do you go to any of the shows near there or know of mopar specific meet ups? I am always looking for more car shows, garage build expertise, etc.. I do have the 318 here apart, looking to get it back together soon.

rumblefish - the stock 318 heads aren't worth putting any money into. For the money, the aluminum heads are way better to use. If SM had the non cnc heads in stock, I would have bought those. The cnc heads were all they had and I am not waiting another year to get a set. 12many - I got a set...

Hey guys, I got my cam specs incorrect. Here are the correct specs: Lift: .515''/.530'' Advertised Duration: 270°/278° Lobe Separation Angle: 112° RPM Range: 1800-5800

8hp70 w stock convertor, 2.76 rear gear, thermoquad from a 340, weiand 8007 intake, probably about a 28” tire diameter. I already have that 272 cam.

Car will mainly be a street cruiser. They are the cnc heads, the description says they are 68cc. I can check them when they arrive. While the engine is apart, I want to get the compression a little better before it all goes together. What size cam should I use then, if you believe the 272...

I didn't want to go too big of a cam and those heads were the only ones they had left in stock.

MLS head gaskets, .040 compressed. KB167 pistons that have a +5 cc volume with a compression height of 1.810". Block has been bored 30 over otherwise, it is stock decking etc. Can't find any details online about the compression ratio recommendation for cam but here are specs: Advertised...

I got a set of SM 68cc CNC heads on the way from the black friday sale. I really wanted the 65cc heads but they were out of stock and you couldn't order them for the sale. Using a compression calculator from Summit, I am showing a CR of about 9.16 to 1 with the 68cc head. I really wanted to...

I read the tech bulletin from Mike's site. Looks like the saddles need to be bored to 7/8" as it looks like they are 3/4" or so. It would be interesting to see if this issue has been fixed. Has anyone emailed SpeedMaster to inform them of this issue and any of the other issues? If yes, have...

Sound German Automotive has the controller.

I am hoping it won't be too bad. Its going to be a lot of fun though when it is done.

I wanted a nice street car, nothing crazy, that is what the road runner is for. It will the a/c hooked up too. The tc is about 2400 stall... 8hp70....

I bought the KB167s, bored 30 over (should be about 9.5 to 1 w/ 65cc heads), auto trans with overdrive. The cam is a Lunati retro roller 20200711 can't take back, in engine already. specs: Lift: .515''/.530'' Advertised Duration: 270°/278° Lobe Separation Angle: 112° RPM Range...

I already purchased the cam kit. It is a Lunati retro roller series..has all the top end parts in one kit with the cam and lifters.

So if you do not use roller rockers, you don't need the correction kit? What about the 273CI stock adjustables? I was planning on reusing my stock rocker arms / shafts from the 318. Is this doable with a hydraulic roller cam / lifters?

What did you pay for a set and what are the specs on the heads? I am looking for the smallest cc chamber I can get. I don't want anything over 65 but closer to 62 would be better. That is why I originally asked about the bare 62cc heads. Can you tell me more about the geometry correction kit...

The 318 is the original engine and I already got the machine work done on the block with new pistons etc. in it. Otherwise I would have went with a new hemi.

The old heads are lead heads I believe, I want the wait reduction too. They aren't worth dumping any money into so I wanted something more modern with the benefits of aluminum. It is a little more than a budget build too, but not radical. That is what the roadrunner is for. This is going to...

stock 71 318 heads.

Ok, I should go with the MPN: PCE281.2146 which is the SB 318 360 170cc 65cc Hydraulic Flat Assembled Cylinder Heads; put my roller spring setup in and sell the other springs? List on those right now is 1165. I would love to go with the trick flows but it is like twice the price and it is a...

I am getting ready for the "hopeful" black Friday sale this year for a set of speedmaster aluminum heads. Just look at the current prices and for a set of hyd. flat tappet heads are 1180ish for the 65cc chambers. The roller heads are 1820! I already have a set of springs from my cam kit; is...

For 1650 are they ready to bolt on? Or is it just the bare heads?

April/May now? That is ridiculous. They are losing customers by this.

I received an email about a few days ago. He said late November release time and price is 1800 a pair. I'll be putting in an order for a pair.

I am on a budget with this motor, plus it is just a street cruiser. I am not going to be above 400hp. I want the dual plane for the lower torque. Is there a better spread bore dual plane to use? I've got a monster build in progress as well for the car in my avatar.

What is the deal about intakes now? I just got a Weiand 8007 dual plane. More and more it looks like everything I have is becoming incompatible with these heads :BangHead: Nov - Dec...I don't know if I can wait that long....

B3 - do you know if they will be available with just the valves? I already purchased springs, retainers, keepers as I was going to get the Sidewinders from Todd at March. He's been trying to get the cores since Feb. and still doesn't know when they are coming in. So it looks like the TF's...

Would you have to run that head gasket or can you run one with a smaller compressed thickness? Also, can someone explain the closed chamber vs open chamber and the benefits/ negatives of each? Are the promaxx/ sidewinders closed or open chamber? I am building a 318 with the kb167s. Will there...
