Thanks I appreciate it. I should be getting the heads back from the machine shop this week. I'll let you know as I may need shorter pushrods, as there has been a lot of changes from the factory setup. Like older style (1974) heads, the rocker spring seats have been machined (I believe .020) and both the heads and block have been resurfaced. With all this I may need a different length pushrod than the factory length.
