If heads are o ringed what exactly does this mean? and what/do you need to do to run them on your engine??
Thanks guys

 

i think i just found my answer but if someone could verify it with me that would be great...
O ringed heads are for nitrous/fi induction, you do not need to do anything to the block just need a different/more expensive style of head gasket.....is this correct?

 

Yes.

 

thanks for the verification man! o and i love your car

 

Thanks. I do to when she's running. She's running good now so i love her.

 

haha, i know what you mean man. Hey by chance do you know a way to find out the combustion ratio of a 54cc head, on a stock 302 block.....and is there away/a head gasket that would lower the ratio to say 10 ish?

once agian thanks for the help
