Hi I'm jumping in for my son who obviously is totally new to Jet Boating ( 19 yr old kid who worked his ass off to buy it ) but still learning on everything else. We he bought a not so good 460 that has ran him in circles. Next is the heads. He has what appears to be the stock steel heads with the roller rocker conversion kit and over sized valve spring . The push rods are all 8 5/8" long and he would like to get some aluminum used heads that can be a direct replacement with hopefully a smaller pocket then stock to up the compression if possible. He already got a Victor manifold so hopefully the new heads better match up with that design intended for cobra jet style heads.
Thanks for your help, if any other ford parts available were listening
