Ok ok, I’m doing something weird. I’m putting w2 heads with 2.055 valves on a stock bottom end magnum 5.9 shortblock with a mildly aggressive hydraulic roller cam and twin turbos. As we all know (I hope) lift has nothing to do with piston to valve clearance, it’s the duration and ramp rates that get the valve in to the piston. Myself and Brian at IMM (he did my heads) are not sure if we’re going to have clearance On the stock piston with no valve reliefs. Even with a huge dish, the valves will hit on the outer edge of the flat portion of the top of the piston. I’m currently waiting for my blocks and relocation kit from Mike at B3 racing and then I can measure for pushrods and check P to V. It’s gonna be close.
