hey guys, i've got the opportunity to buy a port & polished b16a head with upgraded valves/springs/retainers (dont know what kind tho) that flows 327cfm at i think 500 or 600 lift (not sure, but i'll find out today) the guy will sell it to me for $500 installed, and i keep my stock head.. do you guys think its worth it? or should i just save my money and just buy pistons or something since my motor is stock?

 

oh, the head was built by GTP here in Houston, TX

 

I would pick it up for $500.00 bucks. You might want to call Greg and find out for sure if he really did work on that head and find out exactly what he did.
