I'll admit its entertaining to read the back n forth. The forum was kinda sorta slow..then this drew me in. Lmao. One point on a craftsmanship level of critique was what ones work looked like. My 1.6 cents 'in current Biden value' is its about function and performance. Not beauty. Though you know what a to expect when viewing some of the hack chop **** house sometimes posted. So branching from that...I thought of all the things I hear people say and then what I know myself about polishing a chamber this or that port/wall etc... where to grind on a chamber n on n on n on. I just watched the video where David vizard grinds a Vortec head chamber out to a SBC head gasket that isn't round... then I had a commenter on my own video say I should watch DV on why I shouldn't grind a 302 chamber in the area DV says not to on a VORTEC head. Different animals. People dont grasp beyond the surface. The vortec is already CAST with too much from that area. Theres nothing to remove except below the ssr and it's not necessary on the vortec due to the relation/distance of the valve seat to deck. The idea is to ascend at the top cut angle be it 30 ,37...or whatever. Someone took that and brushed across every head on the planet.
