Should I keep these heads?

Ok, hear we go.
77 360
3.58 stock cast crank
TCI 904 tranny with 2500 stall
8 3/4 rear end with 355 gears
225-60-15 tires in rear
old torqer 340 intake single plane
Probably holley 750

This is a 66 Barracuda. Refuse to cut on car. So I'm going with 72 340
hi-po exhaust manifolds.

Looking for at least 13 on the quarter.

This is why im searching for head help.
Thanks.
