Mopar [HEAD] Aches PLZ HELP!?
To be safe I would say that the 302 head was from late 1985 - early 1991.
I usually keep my search limited to 1986 - 1990 vehicles. That way you will know that it will have the 302's... unless someone swapped out the heads in a prior lifetime!
Keep your eyes open in the salvage yards... I found a nice set of Edelbrock heads in there once... for $45 a piece, it was a memorable day! You never know what you might find.
