David, to clarify current timing settings as follows:
Initial 10*
Mech 22*
Total 32* all in @ 2000rpm
Load Compensator with home made set stop for 9* @ 8"Hg

Anything above 34* total this engine starts to pre-detonate even more so with such a fast curve being all in by 2000 rpm.

In my post #17 there is a pic of half the springs I have and none of them are able to slow down the curve with exception to the bottom left but unfortunately the pair I have will not return the weights completely. It appears the after market springs won't slow this curve I need some stiffer ones like those that came originally on these HEI's. Been searching online but can only find aftermarket spring sets, going to a friend's shop this week and hopefully find some there.
