499 performance center thoughts ?

That is an okay price for that collection of parts but you'll never know how good of a deal it is until you run it. The problem with custom built engines is that it only takes one small part to be wrong and the whole engine can go south really quick. So whoever put it together needs to have done an excellent job or else it all gets redone.

I'm assuming those are EZ heads? The ad doesn't say.
Thanks guys .

Andy , that is my worry ... not knowing quality of the build. All of you guys have great valid points. Thank you
