David, thanks for letting us know about the custom machining on your crossram. I had assumed it was just machined for a standard deck height and intake face angles. I know the engine builder that installed the MP crossram on my old Barnett Hemi sure had fits (pun intended) getting it to fit on a block that had been decked around .100"-.120". The MP might be a more cost effective choice for a std. deck and heads street Hemi. It would be interesting to see some testing between the Barton and Indy crossrams that seem to be the most common in NSS.
