NEW to the site. Glad to be in such good company. I have an ohc engine that I have just taken apart the bores look great bored .040 over. I am thinking of just haven it " cooked" checked for cracks then honing it out. My real question is with the cam housing and the head. Being that IM not real familar in taking these engines apart any input would be helpful.How does the cam come out of the housing? What precautions do you have to take as far as the valves are conserned? I was thinking about just sending it out to primetech. Will I get my best bang for the buck there? I actually have two ZH engines and one ZL. Im sure there is a member here with experience with them personlly but I forget your name ? Thanks Chris
