the cams are going in, but after this work gets done....
boring is always a risk, i've done it before, and found that i had problems with valve sticking on my last gsr.
this time, a new one is going in....
as for porting the manifold and the intake heads....you don't want to do that.
the manifold is already sized up to accept the extra inflow, and porting the intake heads creates backflow....there wouldn't be any need for it.
