706 Heads on LQ9?
so as of now i have a 224/224 cam 580/580 lift 114lsa. im running ported+polished 317's right now question is i have a set of 706's if i have the seats cut to take the 2.00 valve and they use the same 1.55 exhaust valve as a 317 and i port and polish them, open up the runners and what not will i see a good benefit in going from the 72cc chamber to a 62cc chamber? i also run a 100 shot through the motor also what do you guys think im just trying to get some more power out of it
