According to GM Shop manuals Cylinder Head Bolt torque is 60-70 ft-lbs. I have found that if you follow the procedure to progressively increase torque in 20 ft-lb increments as you follow the torque sequence you will properly seat/seal the head gaskets. This is true with either steel shim or "sandwich" gaskets. I also re-torque the bolts one additional time within a half hour after I have set the total torque.
bolt them on their the same
That's what should be on it.
nothing. but the intake will be diff.
5.7 is 285 torqe 325 hp 4.3 ? 6.0? 6.3? 454?
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
they came with "186" casting number heads.........
lt1 is a 350
The headers for a 350 and 305 are the same.
NO not even close.
No. Not without switching the cylinder heads. I think it was 89, Chevy came out with the 1st generation Vortec heads, which require a different intake.
