i have recently built a 355 with 882 heads 650 dp and holley intake with just a bit bigger than stock cam 440 lift. my best run to date is a 14.12 spinning the tires. im thinking about buying some new heads and as bigger cam i really want to get in the low 12's if i could but really not sure which kind of heads to get. thinking about around 1000 for heads i know im going to have to make the suspinsion on the car alot better and get some good slicks but which kind of heads and cam could i use to get me there. thanks
