Barring any piston-to-valve clearance issues, what is the max lift stock heads (in my case 906) can handle?



Other than milling/porting/blending the heads and a 3 angle valve job and the comp springs, nothing else was done to the heads which work just fine with the .518" lift of the Whiplash cam. Lift in reality is more like .490" since the rockers are not truly 1.5:1 ratio, there more like 1.4 or 1.45 to 1.
