Head Work

Engine Builder is the fellow that sells the 1.70/1.44 valves. He sells off Ebag as well. Sometimes he has the 340 valve springs too. I agree with Grinder about ccing the head. You may find you want to take the .100 off the block instead of the head or a combination of head/block. .150 is getting into the "new" push rod turf but I have several engines that have that much off of them.
