I have a 1990 formula 350. I saw a pair of AFR 190 used for sale but they are for the LT1. Would these heads fit on my motor??? I was thinking they would b/c we can put an LT1 intake on the car why not the heads. Not tto sure about this, someone help me out here.

 

I believe, but could be wrong, that LT1 heads have different coolant routs. Hence having to modify the LT1 intake to fit stock l98/lb9 heads.

 

I don't know what goes into moding the intake but i did hear that the LT1 flows coolant in the opposite direction of the L98. Oh well it was wortha shot.
