Head gaskets and Eddy head on 440

Head gaskets and Eddy head on 440 - 05/28/13 11:38 PM

Should I stick with the edelbrock head gaskets (.039) and have around 9.7 compression or go with a Mr. Gasket or Mopar Steel shim (.020) to get my compression around 10.2? I just took off Iron heads I had used a steel shim on and there was no evidence they hadn't sealed properly. I really don't want to spend $100 on an MLS gasket(.027) any suggestions? Thanks.

Im switching to 84cc Edelbrock heads. trying to get a little more compression but am worried about a steel head gasket and aluminum head.

I know it has been done.. there on people here that have done it. But not a good idea if you ask me. I would mill some off the heads myself. and use fel-pro gaskets.

How much should I mill the heads? What is usually the going rate to cut new aluminum heads?

How much depends. pump gas ? what pistons? how far in the hole ? My car I have flat top pistons. at 0 deck height. my heads are mill about .080 so I have 71 cc chambers . it give me about 12 to 1. that might be to much for pump gas. so it is something that needs to be work out for what you got and what you want/

Pistons are SRP's about .020 in the hole. I'd like to be around 10.5 so I can be safe with pump gas but in all honesty am I giving that much up by just putting it together the way it is?

Same ones I ended up switching to. I believe they have a slightly larger bore diameter than the regular felpros. I used the regular felpro gaskets the first time, and ended up loosing one. My fault for not checking during assembly, but the fire ring on the regular felpro actually hung over the chamfer at the top of the cylinder bore enough to be exposed to the combustion and not create a perfect seal (I guess).

Anyhow the marine ones are better.

Well your just driving it around..and you don't care about the HP//Yea you can.. Me I have .030 taken off them heads. Are these new heads ..Have you had them checked out ? if they are out of the box new. You need someone to take them apart and check them out.. might as well have them milled then.

My RPM's are milled .050 and they will go more than that. On my old motor, i ran shims, copper coated with these heads for around 2 yrs and didn't have a problem.

Codfish I run the Marines on my 440 also.The 1009s hung into the chambers with my Stealths.The cheaper ones didnt.I went Marine because of 12.5 compression.Its street driven and I run mostly pupm gas.When I want to race or hammer on it hard I use 110 octane mix.Rocky

This , have the heads cut down to 80cc and have someone go thru them , clean up the valve job, backcut the valves and check the clearance of the guides.

With your pistons ABOUT .020 in the hole you lose the benefit of quench. You could run the steel shim gasket, coat them with permatex copper coat.

I have had steel shims on my eddy heads with the copper coat been together for about 6yrs

Just went out and measured with a straight edge and feeler guages and came up with .015-.016 down for the pistons. I'm on the phone now with Summit and it seems Edelbrock has a 75cc RPM head listed. If I can get these heads then I'll be right at 10.7 with the edelbrock .038 gasket.

Seems the Eddy heads are about another month or two from shipping

Good news is the Victor Small block heads have several part numbers and ship time is looking about the same for them. Looks like I'm going to be stuck with 9.8-10 for my compression. I don't really want to mill these heads and all of the shops around here are several weeks deep in work.

other than the several weeks deep why don't you want to mill the heads other than the added issues with pushrod length and valve to piston clearance ?

you could always weld up the chambers some ???

Im not aware of any 75cc RPM.s stock, they have tobe milled about .050 to be around 75cc.

I think the victors are 75cc.

If there are new 75cc RPM heads, thats news to me.

those are the e street a more street oriented head.uses different seat less quality components.from what I have read.
