351C questions
Just picked up this engine last week, came out of a '66 5000 chassis, mileage unknown, first compression check was kinda low in the 40-60 lb. range, shot some Mystery oil down the holes and got better numbers, 90-95 (1-3-5-6) and 89-70 ( 2-4), pulled that head and it looks like head gasket could be the problem, not much if any ridge at top of the 3 bores, no gouges/scoring either. Valves look to be 1 7/8" EX and 2 1/8" IN, the manifolds are the "I" beam style. Are these the "small" valve heads I have heard of? Thnx
