I'm just learning about these. I'm used to pulling the motor up about 4", removing steering linkage, kick down linkage, shift linkage, just to get the drivers side in. i had my exhaust pipe off because i'm installing the dynomax turbos, so i thought I'd see how (or if) they'd fit. Honestly I removed the manifold, 2 starter bolts and slid that back and had the headers up in there all in about 10 minutes.
