Good luck boosting that much compression. 1.5:1 is probably around .188" of the surface of the head and you don't normally have that much to work with and if you did you'd probably crash valves into pistons.
Buy new heads with smaller compression domes.

Lq9....maybe...if so that is pushing it for the comp ratio for a boosted motor

80-89 350. We dont fix those, we replace those with Gen3 engines. Anyone need a boat anchor?
Put some small dome DART heads on there if you just must run that dinosaur.
