Have a set of L92's that have been milled .020 that are going on my brother's trailblazer SS. The cam is a .588 lift, and the heads have stock rockers. Will there be a piston to valve clearance issue with this? Stock shortblock too btw.

 

Will need to know the type of valves (ie. oem or stainless aftermarket) and also the duration and lobe center of the cam.
