Yes they will. The bore is 3.785 so they wont hit
== ==
no they will not
it all depends on the head chamber volume of the 307 heads and the 350 heads that are being replaced. if the 307 heads have a smaller chamber volume then yes, they will bump up compression.
No. The 350 has bigger valves. While you CAN put the 305 heads on the 350, (I can't imagine why you would actually want to) you can NOT put the 350 heads on the 305. Because of the 305's small bore, the valves on the 350 heads will hit the cylinder block.
You must drill the steam holes in the heads to coincide with the ones in the block or it will overheat QUICK!!!
Yes , but you will need a tbi intake to fit vortec heads if you retain the 90 TBI fuel system.
yes ,I have change one out with a old 350 it had lot more power . I used the old heads to with vortec intake you have to slot the four bolt holes .but it will work.
LT1 gen 2 to LS1 gen 3 no
The 1995 350 or 5.7L has a T.B.I. and standard heads. 1996 its a C.P.I. and Vortec heads.

No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
No it is not.
