Which head gaskets for Nitrous?
Which head gaskets for Nitrous? Which would you guys recommend for my setup?
I will be shooting 200-300 on a stock bottom end, while the heads are off i will have them milled for flatness, I will also be using ARP head studs. The heads are 98' year castings
I still drive it on the street a little poblably 1-2K a year
Here's a few i have been looking at
Cometics
Flatout copper
stock GM graphite
TIA

Any MLS style gasket will probably get the job done. Cometic and Fel-Pro both offer MLS style gaskets for these LS1 motors.
You can also O-Ring the block, put a reciever groove in the heads, and use a copper gasket.

Hey i think a cometic is a good choice 
but it will not work with 98 heads without leaking water 
because the slot on the deck on cylinders 3 and 6 if you weld the slot so there perfectly flat then your good .

Harlen went 8's with stock MLS GM gaskets. I run a cometic but the only reason is because of the bore size of 4.03 on my motor. Now you can get a LS2 head gasket or a new Z06 head gasket for the bigger bores though.
