And all you Vortec fans seem to want to ram them down everyone else's throat and make your mistake. A lot of better heads out there for my money. Like the Summit 72cc iron heads.

Lift issue can be fixed with a hand drill at home and a single tool. Valves are as big as any came from GM without being a hi-performance option, and they flow more then the old big valve heads anyways so that's a mute point. Pump gas is boring

We wouldn't be having this convo except for the whole "I hate vortecs" at the end. Its like those old math problems in school where they test you by telling you way too much info that doesn't matter. But since its there, fair game right? lol.
