I have a set of iron, 906 heads, and I'd like to lose a couple of pounds and maybe gain some hp. I don't turn my motor very tight all though it was built to go upper 7k. I leave at 4k, the converter goes to 4500, and it shifts about 6200, going through the 1/8 at 5950. Because of the low rpm, I wasn't sure that a set of Indy's or B1s would money well spent. I'm having issues with compression leakage, and the motor is already O-ringed. It's an alky motor with about 14.5+ compression, and I'm tired of pulling the heads and resealing them. I keep seeing these Procomp heads on ebay and other places, but haven't heard any body that has ever used them. They appear to be cheap in price, and I'm wondering if you get what you pay for. This is just a bracket car and I typically run 5.50's@ 124 in the 1/8 and 8.50's@160 in the quarter.
