So i bought a 2.5 head not sure what year a guy gave it for 100bucks and i was lining up the intake which fits on but theres one hole missing in the middle, pics to show you guys. Oh yeah the block and my truck is 91 i have no idea what year this head is.

 

What? The he'll you talkin about?

 

Show a picture of the intake manifold. The first picture is of the intake manifold gasket and the lower picture is where the gasket lays on the head to accept the intake manifold.

 

howd it turn out? is the 2.5 a dual-plug head? i just replaced the head on my 94, wondered myself if a 2.5 head would have worked.

 

If ur talking bout the small hole on the gasket don't think that on matters bo
