292 head id
I just purchased a 292 head that was made in Mexico but it appears different than othe heads I have had. It has bolts going into the head diagonally from the top on the intake side. Anyone have an idea as to why they are there or if this a correct head? It's the orange painted head by the way.
Thanks in advance! |

Re: 292 head id
Get the casting number off of the head and search the net

Those are plugs to plug smog holes.

This......plugs to block off the AIR injection ports. The casting date will tell you what year the head is.
