Spot-facing for 39gr. lifters

[Massive Type IV]

I cannot afford for a problem to bite me more than once. this is not a hobby. Time is money, especially when you have a 7 month backlog. there is NOTHING worse than tearing back into an engine- nothing.

I know all the lifters were made good. That does not fill my pocket with money for lost labor- 80 hours of it in that particular instance.

I have several cams that have less lift and more duration than the conventional cams that US Tuners use. The cam in Crimson Axes engine is an example. it only liftsthe valve less than .450
