Today I adjusted the valve lash to .018 and rest the timing to 18 BTDC.
I adjusted the the carburetors to 1&1/4 turns out, this produced the highest vacuum 32hg.
Adjusted the idle to 850rpm.
The car performed without issue and pulled hard as far as I wanted to push it! What a difference on the top end performance.
Thank you very much. I feel much bettter about the car and have no concerns now for valve float or sticking. It really runs great now!!!
