Well any well recgonised Group A item, say felpro. Also you will want Group A head bolts. I use non stretch ones on my cvh's, can save you a fortune if it happens again.

15psi's a fair amount for a little cvh.....so id expect to be doing the gasket again at some point in the furure. What sort of power are you pushing,i guess its not running a T2 anymore!?

As said pics would be great!
