What head gasket are you using,& did you O-ring the block, cylinder head?
A Hussey copper head gasket. The block is oringed and the head has an receiver groove. It works good but it still leaks just a little. No head gasket will hold up with just four studs. The cylinder pressure just pushes the head right off the block. We have it apart right now to put three more head studs in it.
Mike Kirbys finding w/a lighter/lightened crank was that it did not improve any ET or HP & the crank did not last as long.
It just made his wallet lighter.
We wanted a torque monster, plus durabilty with all the nitrous were going to put thought it. So, we just cleaned all the flashing and had it heat treated for strength. We did NOT cross drill it.
