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.
No, the 1992 Chevy 350 (5.7L) V8 is not a Vortec engine.
5.7 is 285 torqe 325 hp 4.3 ? 6.0? 6.3? 454?
they came with "186" casting number heads.........
lt1 is a 350
The headers for a 350 and 305 are the same.
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.
NO not even close.
No. The bore size is different between a 305 and 350. The 350 bore size is larger.
the heads should fit as long as your not trying to put them on a big block
350 Chevies were offered with heads made from iron or aluminum.
torque specs 350 Chevy heads65 lbs
the block & heads are the same you just have to pull the 305 out & put the 350 back in
take out the cylinder head bolts
60 foot pounds
no they will not
Not on the head gaskets.
some heads are vis versa
305 heads of course, 350 heads will fit for sure and possibly 400. obviously no big block heads will fit. a 305 with 400 heads gets you a little over 352. 350 with 400 heads is a 383. add and divide
