So could I do this and it work: AFR says that there heads (pedastal mount) are a bolt on heads when it comes to putting a set on a 5.0 roller cam mustang (they can even run stock rockers) but I think they do require hardend pushrods but use the same length. So If I were to say....get pedastal mount heads, and the stock size 6.272 pushrods, and some 1.7 rockers I would be ok. The reason I was wandering about the difference between ped. and stud mount 1.7 rockers was because jegs offers stud mount heads with 58 chambers and the ped. mount 60 chambers and I was thinking a little higher compression wouldn't hurt cause I figure i ill be using some speed pro hyper pistons and I think they only get like 8.8 compression with 60cc chamber heads and i know the 58cc would bring it to 9. But I didn't know what size pushrod to use with the stud mount (thinking the 6.272 stock 5.0 push rods wouldn't work)

If you look real close at a flat tappet cam the lobes are on an angle they are not straight with the cam....
