289 Heads
So this weekend while changing out some gaskets to fix an oil leak I discovered my 302 has 289 heads. I got the head code and date codes of tof them and they date back to dec 15 1963, the head code was C3AE. Searched for the specs and came up wth 1.67int 1.45exh, and 54.5cc combustion cambers. Oh and they have stud mount rockers as well. But this kinda rasies the question of if my 302 is not a 302, it's a 289 that someone rebuilt and swaped in. Back on point here, my question is should I take the heads I have now and cut them for bigger valves (was thinkng 1.94I/1.6E), to take cost out all I need are the stones I have access to a the thing you cut valves with,my mind went blank on the actual name it's called. That and do a good port/polish with the help of my shop teacher. Or should I go get a set of GT40 heads and use them while only doing mild port work on them.
