Here is the victom: 772 Vortec head cross section.

As you can see theres lots of metal you can remove on the short side radius:

Unfortunately theres not a lot of meat on the runner roof or floor to open the port a huge amount (least IMO):

But... the cool thing about it is that when I drilled the walls of the intake runners at the push rod pinch, as shown in this pic, the thinnest part is still .140" thick at the top and the thickest is .198" measured at the bottom of the wall. COOL..

One thing I want to eliminate or at least remove quite a bit of is the bump right below the spark plug. I drilled it to check its thickness and see if there was a water passage behind it and there isnt. I didnt break through till I hit the spark plug hole. No water jacket behind it.. Another coolness thingy IMO


When I drilled the intake runners to check the wall thickness I also found that the deviding wall on the two siamesed ports are just a hair over 1/8" thick. You could prolly knock ~.045" inch off each side of this to widen the ports even more and still have PLENTY of meat left in the deviding wall for structural integrady(sp?).
