I’m sure there is a slight edge in power/durability getting the geometry absolutely perfect. But I’m not going for prostock performance, the 383 in my Dart has been in 2 cars and tortured since 2011 with the same heads a ductile rockers... the sweep pattern on those guys about covers the entire valve head and it’s a mopar 557 solid cam. I spin it to 6800 every time I drive it and it shows no signs of any problems.

That doesn't make the geometry correct. Maybe if you fixed the geometry you could make power to 7200-7300 without more valve spring.

I have been fighting this fight for so long I no longer care unless someone acts like they want to learn. Your geometry is wrong. Fixing it is the correct thing to do. Just because you get away with something doesn't make it correct.

It used to be a PITA to correct the geometry. Now it's easy and quick. Why not fix it?
