I have a 1988 gta I have 93 cast iron heads on it now(they have a stamped ll on the sides i think they are larger valves then normal) my intake fits with that but I was wondering if the 95' aluminum heads will be any differnt or not work with my intake. Also will the 93' heads valve train fit inside the lt1 heads valve train (if not what would I need) my boces teacher said they would I just wanna be sure.

Thank you

 

No

 

Nopeee.

 

Why not differnt port sizes so I would have to get another manifold?

 

Different bolt angles to the intake manifold and LT1s were reverse cooled, so the coolant passages are different.

 

Ok makes sense, I know this is off topic but I have a 88' GTA and a couple sensors missing on my engine and I wanted to know what color wires go to wide open throttle relay,oil pressure sending unit, egr solenoid, cold start switch, fuel pump/oil pressure switch, and the heavy duty colling fan switch. I am sorry for askin all this but the previous owner distroyed the wires on the car and I have been finding each one little by little and any help with even just one plug would be greatly apreciated :].

Thank you
