Oh quench works and works well. Not too hijack but the 318 in wolfs clothing will have the 1.755 comp ht Sealed Power pistons and the decks cut to zero which will be about .045-.055". We may even stick the pistons out of the deck plus .010" or .020" due to the obese 4.180" bore .059" thick gaskets that came in the gasket set. Gotta kill that crevice volume as much as possible. We will then put a custom CNC dish in the top of the piston to snare a 8.9 comp ratio.
The XE256h is an excellent choice of camshaft. I would rather a Lunati voodoo 256 though. Good luck with your build sounds familiar. J.Rob
