anyone know anything about these? I looked at a set and was thinking about getting them. All i know is they are 64cc heads.

Saw a set today they have some pretty small runners, so I dont think they would flow very well but would give you better compression

those are 305 heads.

you would need bigger valves put in them to use them on anything bigger than a 305.

HiPo 305 heads, 58-60 cc. Small intake runners, tho.

We have a set of 434's that were reworked by the engine store. They flow 200 cfm @ .500 lift the price was about $500. they have 2.02 intakes and 1.60 exhaust, stainless valves, good springs and hardened retainers with umbrella seals. I don't have the phone number' but go to for the number and talk to Kent. Also the dome was hogged out to increase the flow. Not bad heads for a small budget team. We added the screw in studs and guide plates to reach the $500 mark.
