40-50 is more like what it will take.

The other issue is trying to find something where the distance to coil bind is within the desired range.

Something like an Isky 8205-SP or 8205-Plus, and then adjust the IH to 1.900(-.050 locks).

More than likely, you could just do the intakes.
The slower lobe, 1.5 rockers, and lighter ex valves probably aren’t having any problems.


Thank You for the advice, I think I'm going to take it and give new springs a try....that seems more likely after our discussion than my next thought of different distributor.

Thanks again, i'll update you when I get some results.
