turbbob, did u do the porting to match the big valves, or did u just have the seats widened?

my guys is doing what he calls "bullhogging" which goes down about 1/2 in to an inch form the bottom of the valve seat. Then I will port the rest and take it back to have the larger valves and cam (bearings, followers, springs) installed.
