Default AFR205 Heads
Will AFR 205 64cc heads meant for a ls1 fit on a ls2? Its probably a stupid question but would be great if answered.

Not really a problem compared to putting large bore heads on a small bore motor. Sometimes that doesn't work too well, but placing small bore AFR 205s on a 4" bore should be no problem. Remember, the 243 head castings that come with LS2s were originally designed to go on top of the small bore (3.900") LS6 engines. Have no fear.
