any that are good and improve the really bad valve angle???

lemme know which ones are superior......................

 

It is hard to find heads that have the small 1.94 intake valve. Most step up to a 2.02 valve, whick will that claer the bore of the 305. World S/R Torquer are the only alluminum heads that will, bt they were designed as a replavemnet iron head, cast in alluminum, so minimal flow difference. The alluminum vs. iron, will give only a 2-3% power increase. Not worth the swap.

Just swap over to a 350!

 

afr makes em in aluminum http://www.airflowresearch.com/


where i plan on getting mine........they put edelbrock and trick flow to shame on flow rates

 

If youb don't want to spend alot of money,get a set of L98 vette alum. heads and pocket port them. They have 58cc chambers 1.94 ints. 1.50 exh. and will clear the 305 bore, use a 350 head gasket with the smallest bore you can find,Ferrera makes one thats 4.060.
