Re: need help with heads..
It's been beat to death around the inernet,,, but... from the GM production side of things....... the modern alternative to the early LT1 heads is the Vortecs.Over 10 years now after their end of production,, the stock iron vortecs are showing signs of age. It's a light weight casting to begin with,, and with poor maintenance valve guides are trashed, overheating has caused cracks, valve / seat replacment... many are not even a good doorstop any more. But in stock form they out-flowed the early duble humps and offered a chamber that held compression down in a flat top 350.
Myself I would rather spend $600 for a set of aftermarket RHS vortec heads that are 100% all new, rather than spend a couple of hundred on a used set, then $200-400 trying to refurbish them. The aftermarket (although costly) has updated the flaws found in the production castings,, better chamber, valves, guides, springs that typically will support agressive hydraulic cams, and valve guides that don't need to be machined to get over .47 lift,,,
a better head just cost more. AFR, Dart, Brodies... it's just money.
