Yeah I figured I'd need to jump the compression up. Any suggestions on what you'd do if you're trying to increase compression and run better heads on a budget?
If you find a set of 66 - 67 318/273 heads with closed chambers, add 1.88" intake valves and 1.60" exhaust valves and port them, you will bump up compression about 0.4 point...
But I would save that for later...
The 64 - 65 heads also have smaller combustion chambers, but different intake bolt angle and size, so stay away from those....
