Head Gaskets For 300 Shot of Nitrous ?

[434 nova]

What head gaskets should i use for a 300 shot of nitrous. I have a Dart lttle m block with a 4.155 piston with no steam holes. Can i use a head Gasket that has steam holes in them even though my block doesnt have them? Can i get some part #s also. Thanks for the help.

Cometic MLS only!!!!

Do you have a part # you could recommend.

I use Cometic MLS as well. Rock solid reliable.

Steam holes in the gaskets won't be a problem.

Do you think felpro 1004 would handle a 300 shot. That is what i had before on the motor

Sounds crazy but yes that felpro 1004 will handle a 300 shot. Ive done it for an entire season on a felpro 1010 wich is the same gasket design as a 1004 but has a thinner compressed thickness. I have actually sprayed 350+ on a set of used felpro 1010s and they held up fine. I wouldnt recomend doing that but I did it because I was poor. Cometics would be ideal but you can do it on the felpros you just would have to worry about it everytime you took the car out. Id rather have the cometics and not worry about it.

The FelPro MLS is another great gasket. We have spayed well over 500 hp and in turbo apps used up to 32 psi without issue.

i am with sam (tubbed truck) on this one.
had real good luck with the felpro 1004 spraying 300 on a plate. steam holes were in block but not head. no problems.
for small blocks, i strongly recommend retorqueing the heads after a couple of heat cycles. the long middle studs seem to loosen about 5-10 lbs after the initial break in.
