is the felpro 1142 the gasket i need for my 383?
going to run 20psi so thats the reason for steping up to the MLS.
Thanks

 

Not knowing Felpro's gaskets by heart, are you referring to the Intake gasket? You may want to do a little reaseach. I don't know the exact gasket my motor shop used on my setup, but it was some kind of less dense gasket with the 3M sealent on it. The 3M sealent is key for boosted motors. But again, I am not too knowledgeable on it, so more digging will need to be done.

If it is a different gasket, then I apologize for giving info on something you were not asking about.

 

I use a new stock and know of serveral high boosters that do to. if i remember correctly, the felpro one is paper or cardboard and seemed cheezy.

 

I have used, and will continue to use the 1074 head gaskets. The Felpro stock replacements blow out real easy!

 

guys i am talking about a new felpro head gasket which is made out of multi layer steel....here is the link

I have a set for my motor, but I'm also not going to run 20psi. I think a lot of guys running high boost use Cometic gaskets. If I ever get my motor together and in the car I'll let you know how well they work. If they blow out the first week then I'd say don't buy them

 

they are just like cometic..but supsosbly better...

 

Thought you were talkin intakes

Head gaskets i use 1074s

 

if they are better and will work..id like em too. they are even a little bit thicker...i wanna hear anything i can with these....so far im planning on 1074's but if these are a little better Ill go with them. Im only going to run 10-14psi

 

None of those listings is for an LT1. LT1 is NOT a small block Chevy, and you cannot just use a SBC gasket. You need the LT1 -specific gasket. Looks like they don't have one in the MLS yet.

 

1074's will be absoloutly fine at those boost levels. I've run mine up to 18 psi!

O...ok then.

 

went with cometics

 

i blew my 1074's on 14# with my 383... cometics never failed me.
