Hi, Dave in UK, I have a 545 in my Dax Cobra, the heads are Trickflow streets ported by Scott Johnson in Tacoma, obviously the weight saving is one of the main issues, I get the feeling that all out horses is not your goal, I run a Comp xr292 solid roller, Dominator 1050, and a Victor Manifold, I would recommend the TF heads but the P51 gives far more options ultimately, horses for courses as always. dave
