Can I use ls9 head gaskets on stock head LS1?
Wasn't sure if this was possible or if the bore size is different. Trying to figure out what my best option is for head gaskets on a stock block ls1 running 8-10lbs of boost. I'm also getting ARP rod and head bolts for extra security.

^isn't the bore diameter something like 4.090 for those ls9 gaskets? Is that going to be an issue with a ls1 with 3.9xx bore? I wouldn't mind using them, they seem cheap enough. The studs are a good $100 more. Is there a benefit to having them if only pushing around 16-17lbs down the road?

Unless you have very good reason for not using studs.....use studs.

I'm also considering getting the 317 heads along with the ARP studs just to help bring down the compression. If I go that route is there going to be an issue with the bore size on an ls1 using those heads and what gaskets would you run with the 317's?
