The test will determine whether I buy a set or not and they need too be more than slightly better than the 57s and up.If they can make several more HP and ft lbs of torque then I'm probably a buyer.

Just need a set of Fentons for testing.  Have been testing a few of the header designs that are here on various engines as I go along but a serious test on exhaust systems will take place on a near stock +060 312 once the engine is reassembled.  That engine is a being a bear right now in that 4 of the 5 cam bearing holes are undersized (by as much as 0.006”) and to compound this issue they are not aligned from one end to the other either either.  Will be boring the cam journal holes in the block oversize in which to straighten the holes and get the camshaft to rotate freely and without carving on the bearings which would have created an excess of bearing clearance on the rear cam bearing if done this way.  Still hope to have this particular block ready to preassemble in a couple of weeks or soon thereafter.
