I am going to replace my stock head gaskets with Impala head gaskets when I install my cam and port my heads. Later this summer I will be spraying a 125 wet shot, and was just wondering if anyone has experience using the Impala gaskets and N20?

 

I'm running Impy head gaskets with my stroker and a 200 HP shot of nitrous with no issues. FWIW, head gaskets should have pretty much no bearing on whether or not you run nitrous.

 

Head Gaskets will increase both your dynamic and static compression ratio. That will directly affect your cam... vice versa. Mr. Gasket makes copper gaskets at .020 They are re-usable and seal great!

Also, your stock deck height is .025... add .020 for the copper gasket and you'll have a quench of .045. The best target for quench is .035-.045... you'll be at the edge of the sweet spot.

 

Since when is that a bad thing with nitrous?

 

My Impy gaskets work fine. 150 dry shot.
