Are these Brodix heads ruined?

My friend has a set of Brodix heads i can get them for $400. I was going to put them on my 400sbc for my tbucket. The guy he got them from said they are stage 7 porting whatever that means. It appears to me that someone overported the intake runners and i'm not sure how the gasket would seal. Here's some pics of them. Thanks in advance Aaron

They're OK, if any leakage occurs it will be port to port which is not a significant problem.

Don't forget to drill for the steam holes if they aren't there already. This insures that hot pockets don't form at the upper cylinder walls and head decks at lower RPMs and power settings when the pump isn't spinning fast enough to blow out the steam if there aren't these passages to vent the pocket.

I'd be more concerned about the exhaust sealing than the intake. I'd save your money $400 is really not a great deal for a used set of those heads. Its a good deal if they are in good usable condition, but it looks like someone leaned on them hard with a grinder (not to be confused with porting).

They look alright, but idk if i would buy them. It looks like someone went a little overboard with the porting, or grinding, whatever they did. They should work fine though. It's up to you. 400 isn't very expensive for a set of heads.

The specs don't matter much any more, nothing is as it came from brodix. That port looks way too big unless they're running something like a 2.100" intake valve, maybe bigger. Just keep an eye out for some iron eagles or something like that, save the worry and hassle for someone else.

I wouldn't want the intake gasket protruding into the port flow area either, I would think about turbulence/reversion at the transition. May not be a major issue, but gives new meaning to the term port matching...

Pass on those heads. Heads that old were not made from the greatest alloy.

You can just cut out the gasket between the common intake runners. It does not really change how it runs if you have a big cam.
