hey guys just want to know id i need to use new head studs when i bolt my engine together considering it will be higher comp and also whats the difference between xc and xd sumps

Unless your running still compression? No you don't. I've got 11.5:1 using standard felpro gaskets. I had issues with the felpro o-ringed ones. Thats got me buggered why? The stock head bolts will do the job easy.

[edit] The sumps should be exactly the same.

All i use is felpro head gaskets
VPW sell copper head gaskets but i think they are dear.
