Selling a Great Set of Small Block Chevy Heads. These are 58cc Heads that I had done for my Camaro 350 Project and then decided to go a totally different direction! Never bolted on to an engine - they're still bagged from the machine shop! ALL the machine work was professionally done:Ported & Polished Intake & ExhaustSurfaced/PlanedMachined for Larger (1.94 / 1.6) Valves, Including New Valve Guides & SeatsMachined for Screw-In Studs, Guide Plates, & Roller RockersCasting #376450All this work was done to make them build High Horsepower on a 350 block. They flow WAY better than stock and the smaller chambers bump up the compression for more torque. You will read that 376450 heads were crap.
As Stock Heads, that is absolutely correct; the Intake & Exhaust runners were way to small - They were built for fuel economy.
With Professional Machine Work however, they have TONS of potential. I've never had them flow tested, but the engine builders and racers I've talked to say making 350-400 HP is no problem when you put these on a 350 block!!Almost $600 worth of machine work done - Asking $335 firm
Can deliver near Tecumseh or between there and Lincoln.Thanks!
