Head gaskets
 

I'm thinking of running some Nitrous on my small block chevy. Now I'm using Fel-pro head gaskets. Should I O-ring the block and use copper gaskets or would cometics hold up ok?

Spray
 

NOS is a two sides sword, it makes power and does break parts. I put cometic gaskets in my 496 and have not sprayed it yet, but I will with a 150 shot .. But guys that run alot thru their motors like the cometics. Might be an advantage to o ringing the block.
Good Luck

how much nitrous you wanting to spray ?

Hey David,
I don't want to sound dumb here but I'm not real sure. My car runs low 5.60's in good air. I'd like to get it in the 5.20's in the middle of the summer. So any info. on that would help too.
