well the valve seals in my 305 tpi are going. and i was wondering what other options of heads their were out there? what have people used. i want to try to get a little more power out of the ole 305. but dont tell me "drop a 350 in it" id like to do a turbo 305 build at some point but in the future. basicly should i try to find some 350 heads, or just rebuild my old ones?

Replace the valve seals. Easy job. $40 worth of parts and an afternoon, you're good to go.

The only alternative to your '081 heads are the Trick Flow 175s, which aren't worth it, or converting to milled Vortecs. do the valve seals and move on to the usual bolt-ons.
