Can anyone tell me if these heads are worth buying?

Looks like a very good deal.

Also, his feedback score is 1175 with 100% positive feedback. (This is important to me)

I agree. $400 for a worked over set of heads like that is cheap. Too bad they aren't 76cc heads though. I prefer going with the bigger heads to keep the compression reasonable. I also think its easier to find domed pistons to increase compression if you decide to go that route..its certainly cheaper than buying a new set of heads.

they are not very good for performance.

bigjim, why do you say they arent very good for performance?

they were heads made for a 305. The only thing that makes them increase performance is the 60cc chamber(increased C/R) but they don't/wont flow enuff to satisfy a 350.

i agree, buy the time you spent the money porting them out to get the flow you need for a good performace setup you could have just bought a good set of protopline or dart performace heads that will be better than those heads if they were ported. i think protopline is the bang for the buck.
