i got a set of ls6 heads and ported them myself ... took about 6 hrs with a die grinder. the openings are huge now.... you ever think about some aluminum wheels?
yeah id love some al 20's but dont wanna pay for em. Its cool if I run around on some heavier wheels now that I have my al 16s for the track. Why... you got some...
are you running the heads now, i bet it made a big difference
