Mike, i'm sure the gauge should be right its a russell liquid filled, it read the same cold and when the car warmed up, I did a compression test 1,3,5,7,2,and 4 got rained out so i ahve to wait to do the other 2 but the other 6 were all between 120 and 130 so im gonna guess no bad valve.
Sam, i haven't popped off the valve covers yet to see if any of them are not moving as much as the others, As far as the plug wires go i had a q jet on it when i first started this project that dumped a lot of fuel turning the headers red. they are 8mm comp wires would that be enough heat to damage them ?
