OP you might just want to put the 4 brl on now and see what its like. It should certainly wake it up but IIRC the heads were different on 2 brl vs 4 brl cars also so published 4 brl HP would be less with the smaller heads

With that said when I put a 4 brl on my 327 210 hp 2 brl motor it really woke it up.

If you do go cam, lifters, new heads at that point you would want to hone, re-bearing and ring the motor. That total cost is likely as much if not more than a new crate motor with modern heads, 1 piece RMS and full hydraulic roller cam....and a warranty. I found this to be the case when I needed to rebuild my 327.

Check out Blueprint Engines. What I got. The 411hp/413tq REALLY makes a difference over mid 200hp motor.
