And so the upgrades are starting to come together...Heads will stay the same for now...My next build is hopefully a procharger motor...
You're leaving a significant amount of power on the table by not spending any money on the heads. I guess I don't understand what your goal is, since it seems to have changed from the original post.
5's is still the goal ....We weren't far off last year, and with a burnt head gasket and blown header tube, there should be some power left on the table. But yes, heads were what we originally wanted to do, but I think we will change it up more next year and with a procharger, we don't need super good heads.
Money was the other decision. New heads were outside the budget, and the porting quotes I got seemed pretty high to me. So we went with new pistons and head gaskets to get a little closer to max compression. We will be starting the season on 50/50 race fuel and getting everything dialed in from there.
