Default G5X4 cam stock bottom but....
Im undecided... i have a set of 853s,317 and 5.3 heads 862s i think ... what would you go with?

I want to get the best performance and dont want to lower the compression from stock.

Going from what you have, I would go with the 317's. Same ports as the ls6 heads. You can have them milled down to keep your compression.
