You still running the original heads on that 351?
lol yea im doing a test to see what hp/tq #’s get out of them at 5, 7, & 9-10 lbs of boost since i havn’t seen anyone post turbo’d #’s with the stock heads. I know they are severely restrictive on the 351 & flow about as much as a donkey exhales. I have a set of AFR 205’s ill be slapping on there later.
