Thanks guys, I've had the cam and rockers and a donner vehicle for a couple of months already and have done a bunch of research. so now it's time to do the job. Through everything that I can find, the head is the same just a different cam, dist, intake - etc but as far as I can tell takes the same head - I wanted to know what u guy's though being around Yota's WAY more than me. I'll ask Marlin or LC tomarrow... Thanks Again
