I just recently purchased a new big M 555 dart short block with scat forged crank, competition forged rods, and 2618 probe dome forged pistons. 4.560 bore with 4.250 stroke. 6.385 in rods. compression height is 1.270 in. dome height .110 and deck thickness is .210. I am just getting some input and suggestions on what heads i should use. It will be going in a street rod on pump gas that will occationally go down the track. I want the best heads that will flow a good amount of air. I will probably just run a single plane intake.

I'm building a similar engine, and am using and would recommend a set of AFR 315's-I would mill them so that you are running 10-10.5:1 Compression, add in a Cam in the 250-255 @ .050, and voila', instant 700 h.p. +-

haha i might sound stupid but i kinda have a 2k spending limit on the heads being as i went big on the block and i dont quite need anymore than 700 hp for the car im building. Ive heard the dart 325 or 245 pro 1's are good just trying to find out what else is out there.
