*****, on a Gen 2 use the stock intake gasket for a template. Match the intake ports up to that, and blend the valve pockets into the seats.
On the exhaust, don't match the exit to the stock gasket or you'll likely hit water. Leave the exhaust shape as it is, but you can widen the ports about .050" per side at the exit. Blend the pockets and fully polish the exhaust ports.
Get a good multi-angle valve job from a reputable machine shop, heck, I'd probably have them put 2" intake valves in it before blending the intake pockets. Why not? If you're to go to all the trouble to do it, do it right.
On the chambers, blend in the ridge that's on the intake side of the chamber, and remove any sharp edges that could glow and cause detonation.
