used aluminum heads?

i have the opportunity to pick up a set of used trickflow t/w heads for an amazing price. Supposedly 500 miles on them. Any way i am going to look at them this weekend and am wondering what to look for as far as their condition goes?

Also, does anything special need to be done to put a set of used heads on a BRAND new motor (block)?

It's hard. The main things to look for are,

Are the heads warped are the decks flat? Did the guy pop a head gasket and is selling them because of problems? If you have a straight edge take it with you.

Also what's the condition of the decks? Are they rough or scratched at all? If so they might need a light mill to clean them up.

You can try taking some alcohol and pouring it in the ports and see if the valves seats leak.

When I got my vic jr's I got them from a well known local guy and I took them to a machine shop and got them checked for $25 and they were just fine. So if you can't get the guy to take them to a machine shop and have them checked you can look at the above and try that.

Like mentioned above take a straight edge with you, also instead of alchol I prefer brake fluid. Alcohol evaperates quick giving a false reading of bad seals imo. Tell him you'll take them if he takes them to a shop and has them checked out on your bill.......

Peeps usually O ring a head to help keep the gasket in place under boost conditions.

If you have a prob, the O ring keeps the destructive pressure contained causing damage to head, piston, rods, etc.

A head with no O ring will usually blow the gasket under those conditions.

Peeps usually think the gasket on a non O ringed head acts like a saftey valve or ...... the thinking is ...... "I'd rather replace a HG than a piston, etc, etc, etc".

Don't get them without having them checked at a shop first. They could be okay. The O-ring can be milled of if you want.
