I don't know much about this topic, but I can get a set of heads off of a 5.7l engine for almost nothing. The casting numbers are 810. Would these fit on my stock 305 or would it be a waste of time?

WASTE OF TIME
the combustion chambers would be huge compared to your small 305 head combustion chambers, you would lose alot of power and torque, esp down low

Sorry to jack the thread, but what kinda compression do you think i could make with stock 305 heads on a pretty much stock sbc350?
I recall reading about guys putting 305 head onto 350. The problem is you've got to get them to flow, so I think they usually put in bigger valves when they do that.
the best heads from a 305 to put on a 350 are the 416 casting numbers. they ran from 80 - 86, mostly in caprices i think.
i think the compression is around 10.5 - 11?
it gives you ALOT of low end torque with the increased compression but from what ive heard it starts to choke around 5,000 - 5,200 rpms
