Works in a G Body

Installed these headers on a 1986 Cutlass Supreme, with a 355 SBC with angle plug aluminum heads. Plenty of room for spark plug boots and fits between the frame rails nicely, only had to notch the upper control arm a touch and the header on the driver side going under the body. Solid choice for budget long tubes.

Can these be used in a 80's Monte Carlo with engine setback? The biggest problem area seems to be the passenger side clearing the upper control arm. Also wondering about clearance for a kickout oil pan and lower control arm mounts. Thanks
