516 head question
I was worried about them being too thin so I didn't end up doing the plunge cut and larger valves in the 516's, just a quick clean up with a cartridge roll. I did do the plunge cut and a lot of grinding on a pair of 346's for my 400 build, but I retained the stock valves. The pictures loaded out of order. The 516's are in the middle.
