They're decent heads- were used on the discontinued 300 HP 350 HO crate engines up until Vortec heads were used. The Vortec heads bumped the HP to 330 on the HO engine- although I'm not positive ALL other specs were the same.
Start a fresh thread on the engine build- that way it'll get better exposure.
