The "problem" with the '86 is that the pistons are true flat tops, no valve relieves. This causes a clearance problem with valves during the overlap period of the cam (piston TDC during the exh-to-int cycle), not because of lift.
You could install any cam you select but a PtV clearance check would be needed and notching of pistons, most likely, would be required with the OEM pistons.
The other alternative would be to upgrade to TW heads, they are specifically designed to support the Stg 1 cam w/out notching pistons on the '86. My 2¢.
