When it comes to heads for the 455 does TA performances heads or P&E's Bulldog heads have an advantage over the other. The price is about equal and it appears that the flow numbers are close from what I have seen especially on ported examples. But have there been any tests comparing the two with identical setups? Since there are really not many choices you would think it would be an easy decesion but unless someone has actually really compared them it is not. With chevy, ford, and mopar heads you can find comparisons between all the heads and that makes it a bit easier even though there are hundreds of choices. Memphisblue Hayabusa
Thanks, I didnt know anything about that, and you are right bulldog no longer makes heads. Memphisblue Hayabusa
