which heads for a 408ci?

607 hp isn't impressive ? anyways i've been there and guys running 600 hp are usually running in the low 10's to high 9's with a totally streetable 10.5:1 2700 to 3000lbs a body. you can spend the money with eddy's or commando's but for the money you aren't going to come close to those numbers without a real head like indy's or w-2, w-5's. whoever doesn't think 607 hp isn't a big deal is crazy. that article from carcraft doesn't show the whole engine build . like i said in an earlier reply they made 583hp with a single 850 on an m1. i'll email you every article of the build if i have too! i run 11.5 in a 3700lbs challenger with 4.10 gears. race weight is 3946lbs! i'd like to see a combo with eddy's on it run those times, oh yeh i did it myself it went 11.8. do not spend the money on those other heads you'll be chasing ghosts. spend your money wisely ! i know i didn't the first time. another thing with aluminum heads is it says you have 11.5:1 but it's the same as having 10.5:1 with cast
