Help identify aluminum heads
Took a minute but i found that part number (mahle changed their part numbers a while back and yr pic has the old one)
I dont see how they got 500ci or 10-10.5:1 compression. Mahle pistons arent dished, they have large valve pockets. maybe the motor does have a 4.375” stroke and its actually a 520??!!
