I was at the machine shop after work today, dropped off 2 heads that I ported as far as I dared. I admit to not being a porting "expert", not by a long shot. these were my 1st 2 serious attempts at it. IDK if I wrecked the heads or not. I'll find out soon. But, as I told him what I wanted done to (one of) those heads-- if it survived my butchery attempts--- and my goals for this engine, he looked at the sheet I gave him that came back with "Wow-- that's stout..... for one of THOSE engines anyway"...
