Having just gotten out of my honda, I know that one of the performance upgrades was getting bigger fuel injectors for the car. So, applying that to this situation, I would go with the bigger injectors.

ok, im just kinda worried that the large injectors will be to much fuel maken me burn lean, std 305 heads are 64 cc, these are smaller then that, see my concern?

Wouldnt too much fuel make you burn rich?

whops yes, rich, sorry thought one thing typed another, and after thinking abou it last night, the moter is going to "take in" as much air as a 350 would, so it should get as much fuel as a 350, its just going to compress it in a very small space

And the compression ratio would therefore be raised corroect? So you'd have to run a higher octane gas to prevent detonation.. OR retard the timing a bit
