I am selling a monster top end set up for a sbc. Aluminum Heads, Intake, Shaft Rockers, Valve Covers. These heads are not for the weak at heart or a weak motor for that matter!! They are an older set of Aluminum Dart Race Series 220 heads that have been Fully cnc'd by Dart to 248cc intake runners. Monster intake and exhaust ports!! They are 72cc combustion chambers, Raised intake runners, 60/40 valve spacing, 2.100 intake valve, 1.60 exhaust valve, and spread port exhaust. I do have custom ported 1/2" thick billet aluminum exhaust adaptors to mount regular headers to these spread port exhaust heads. These heads flow like crazy and make KILLER POWER!! The heads will come with a Victor high port intake that has been matched to these heads plus, an older set of Crower stainless steel shaft mount roller rockers with .250 offset intake and .80 offset exhaust and a set of black Proform valve covers to button them up. I had this set up on a 408" sbc and I was running a solid roller cam with 640" lift. springs are good for up to 700" lift. This set up made well over 550 horsepower on pump gas with only 10.1 compression. There is nothing wrong with this set up EXCEPT that two roller tips will need to be replaced as they have flat spots on them. I just spent $800 on these heads for a complete valve job with new bronze guides and probably have only 200 miles on them. The only reason I am selling is because I spun a couple of rod bearing on the engine and I will be changing to a new motor and this set up will be to big for the new motor.
