Block and head groove?

So the 1008 work with the o rings?! That's great to know thanks for sharing!

You should call someone like SCE gaskets and talk to them. I'd hate to see you ruin an otherwise nice engine over a pair of 80 dollar copper head gaskets, wouldn't you?

If I were you, I'd calculate what static compression is.....I bet somewhere under 9:1 and save some coin for a blower. That engine was built for nitrous, or forced induction. A 6-71 stickin through the hood would be badass.
