Default What are they worth?

I came across a guy selling a pair of "race prepped" 799 heads with full port and polish, upgraded valve train etc. Wondering what they are worth and what a fair offer would be?

Lots of unknowns. What are the specs on the valves and springs? Are you changing cam in your engine to support the modifications? What are the flow readings on the heads? Will the head change require you to upgrade cam?

You need to know all these things or you could just be spending money that will provide no benefit for you.

Be careful with "guys" and selling ported heads. Just because some guy has a grinder and heads doesn't mean he knows what he is doing. You can easily mess up heads and they be worse than stock.
