I'm rebuilding my 94 LT-1 and have been reading bout the different head gaskets everyone's been using and everything. Now my question is, how much compression do you actually gain with the impala ss gaskets. And what is the benefit of the felpro 1074 head gasket. The motor is gonna be a 355 and will be around the stock compreesion. Thanks for the help

 

If you go with a thinner head gasket you can gain up to one half of a point.

You mention the 355 will be around stock compression, but how do you know that if you haven't selected the head gasket?

 

just because right now i was planning on using stock replacement head gaskets and just thinking it'd be about the some with very little difference. I just haven't deciced yet what to go with yet

 

Go here and play with the calculators. http://www.wallaceracing.com/Calculators.htm

You running a stock camshaft? How about a build list?

LT1's are compression ****** and I like it. Joe and I are both over 12:1 in our "street" LT1's.

Cam specs are 230/236 .510/.520 lsa 112. Pistons are flat top four valve relief 30lbs accel injectors. Stock heads beehive springs, 1.6 roller rockers

 

I would use the victor reinz 5898 gasket; that is what I have on my le1 355 with no problems.

 

alright i'll give them a try thanks for the help

 

le1? might want to edit that post
