Alright, I made the monthly trip to Houston Performance(4.6 & 5.0 Heaven) to get a price idea. I haven't seen that many mustangs in one place since FFW Houston. I asked him about porting my NPI's and he asked me why I didn't want PI's because they "flow better ported" despite what I told him I had heard from you guys. As he showed me around the place, I saw two 4.6 blosk that were well ventilated, one out of a supercharged saleen who decided to drop a 150 shot on the just tuned setup, taking out a part of the top of the #7 piston head. Another was a cobra block that threw FOUR rods, that block was swiss cheeze. Anyway, he said the heads with complete valve job, backcut valves, 3'angle valve job, bowl work, valve seats, port, and polish, assembly would be $750. I asked about a flow sheet and he said he'd do it no charge, which I assume is standard but he responded as if few people asked for them. The price, I assume would not include taking them off of and putting them back on the car. But it seems ok. he said it would take a week. he said if any of the parts needed replacement they'd do it, i'm sure at an additional cost. But he showed me his mustang whish is supposedly the fastest N/A 4.6 in the country at 11.4 or something like that. He was pulling the engine to put in a 5.0 stroker kit for the block. I tod him that he'd have to change the 4.6 on the side soon then. But the 5.0 modular sound cool. I think if i have the cash during my rebuild(one day soon) i'll do it. he said it would cost several grand. Maybe not too soon. Any input on the pricing would be great. Thanks.
