Rudimentary valve clearance question.

You gotta check it to be sure. I had stock pistons .040 down in a 383 and had my 452 heads shaved .060. With the .484 cam on a 104 centerline I had just over .100 piston to valve clearence which is at the limit. I like to use 2 light springs on my heads and push the valve down until it hits the piston. I check both of them every 5 degrees thru the whole overlap period. Good luck and dont forget the Eddy heads will also have the larger 2.14 and 1.81 valves. Ron
