Terry,
I did as you suggested and confirmed that the valves began to open when the engine pulley was moved 2-3" to the right and left of the bump on the crankshaft pulley. Number one exhaust when the engine was rotated clockwise and number 1 intake when rotated counterclockwise. So, I am assuming that the cam timing is correct. Would using the earlier style valve springs contribute to a loss of compression? In the Ford manual the later springs have 7-10 pounds more closing force than those used on the non rotating valves.
