Will these Rollers fit Gt40 3 bar heads (Cast Iron) What all is needed to make the switch? Do valve spring need to be changed, Push rod length? or is it pretty much a direct swap? I'm running a E cam. Tank you
I'm not 100% sure if they will fit the GT40 heads but I don't see any reason why they wouldn't. I added a link for you to read on a forum that might help you. http://www.streetstangs.net/archive/index.php/t-9305.html As far as the everything else goes they are a direct bolt in replacement. No need for different size push rods or valve springs. I will say if your push rods have some mileage on them I would replace them with the rocker arms as they are inexpensive but invaluable. Let me know if you have any other questions.
