Yes you can. Be wary that if there is much of a difference in combustion chamber size you will be affecting the compression ratio.
As an example, most of the 350's in 1975 had the 76 cc chambers. If you put a set of 58cc heads on that block, your compression ratio would go from about 8.5:1 up to something north of 10:1. This would make more horsepower, but is not pump gas friendly.
the heads should fit as long as your not trying to put them on a big block
The 1975 Chevy LS9 350 with a four barrel that I have is rated at 165 hp from the factory depending on the type of heads you have on it, it could be more.
bolt them on their the same
That's what should be on it.
NO. They are completely different
nothing. but the intake will be diff.
what is the timing specifications for 1985 Chevy with a 5.7 liter 350?
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
they came with "186" casting number heads.........
lt1 is a 350
no
The headers for a 350 and 305 are the same.
