As an engine builder and a racer I’ll put in my 2 cents. I’m personally all for the head Eric has gotten approved. The amount of hours welding and epoxying the castings we currently use isn’t very cost effective, and while I do know that’s why the costs are what they are I feel like this head being legal for use in super stock is nothing but a positive and as stated Eric sells them to anyone and they fit the rule of “generally available”. My biggest thing I keep seeing being brought up is the angle plug situation so here’s some insight that seems to have gotten missed. NHRA has allowed angle plug replacement heads for gm engines for MANY years but a lot of people missed this. Gm years ago produced an over the counter replacement head that could be bought at any gm parts supplier or dealership, there were 2 part numbers, one was a 492 and one was a 292 and they were available in an angle plug and have been accepted by NHRA for a long time. I’m sure Dwight could probably look back in some old tech bulletins and tell us exactly when they were first accepted. My point and opinion here is this, I think a head that is generally available and more user friendly to get to the finished product is a plus all the way around.
