if you are goign to do anything with the 305..

get a camshaft.. they first one have/were natorious to flat cams due to their soft make up.

yes those head will work.. but hte major problem is this.

stock 305 heads come wiht a 58cc chamber.. the smalled 350 is a 64 oem..  most stock 305 run betwene 8-8.5:1 c/r wiht a 58cc head.. going to a 64 head will drop your comrpession below 8 which kill what little power you have.

if your dead set on building a 305.. heads are a good investment. OEM suck big time!!!!  300hp out of a 9.5:1 305 pretty easy. andyou have a very square motor.

i have used these on a 305 http://www.summitracing.com/parts/WRL-042650/

I remember back in high school when it was cool and exotic to put 267 or 283 heads on a stock truck 305  LOL   Thought was: small chamber = more compression = HUGE power!!  How wrong it all was. Tiny, tiny ports, too small of chamber, tiny valves = lots of power robbing.
