There is a temperature switch that goes in the driverside head up front between the
#1 and #3 spark plugs. Reason it goes there is because that is the side GM ran the temperature wire too in the wireing harness.
but to answer your question, There is no left and right head, it does not matter.
At least no with that year of heads.
The 4 cylinder has 1 The 6 cylinder has 2
yes it will
I was unable to find that exact number at mortec.com, however if you have a set of 3991492's, they are very possibly a set of 70-up LT1 camel hump heads with 64 cc chambers. These would be valuable heads.
if ur lucky it may have came stock with camel hump heads with 10.2 compression and it will purr....
These should be double hump heads. They are very sought after heads.
Yes.
Not on the head gaskets.
take out the cylinder head bolts
The deck is the surface to which you bolt the cylinder heads to.
lt1 is a 350
In the cylinder heads.
