Al,
My friend just completed a Max Wedge 64 Belvedere. This is a great example, according to my friend, Chrysler makes a replacement head to this combo already but they use aftermarket companies to cast them I understand. The original was a #518 casting and the legal replacement is a #518m. So you see some of the "participating manufacturers" are already in the aftermarket arena. This keeps this oldy but cool combo alive!!! We tease him sometimes and call him "Mr Supercede"

We had an original set of 518 heads and they were good but not nearly as the revamped 518m. Bischoff made almost 800hp with that motor on the dyno last year. I think with some wideband tuning it'd go well over 800hp's. U should have heard this thing in the dyno it was WAY WICKED!!!!

What a cool factory race engine two fours giant ports buncha compression.

I had some respectable super stock racers tell me the combo was dead!! Not true, I think this car will go 9.50's in SS/DA If i can get him to lay into it a little.

I agree with Mike and the huge point is... how do the dead manufacturers like Pontiac Buick Olds AMC dont get any of that without the aftermarket companies???

Or any other combo that doesn't have a supercede or replacement that's hard to find or high dollar. Chrysler could stop making this 518m head, where would he be then??? What justification is there for others; I dont know somebody tell me. I also agree with Mike's point that the original combos need to be left alone for the guys already running them. The replacements need to come with horsepower if allowed especially if they're "better".
