Just the one planed head? ;-) Why doesn't it run on pump gas? Power completely depends on a variety of things you haven't specified. What heads are they? Are they the factory heads with a clean up or something better? What is the I/E duration and lift of the cam @.50? What is the compression? Performer or Air Gap? Roller rockers or standard (and what ratio?)? Rev limit on the engine?
They are fun motors (I had one +30, edelbrock performer intake, headers. twin 2 3/4 exhaust, mild cam, standard heads). Went ok, heaps of torque, ate tyres, grunt in any gear. Wasn't a big HP or high revving motor though.

If it's going into a Falcon then get some decent tyres and suspension. Mine was a fan of trying to go straight when I was trying to turn hard (e.g. round a roundabout). Also how it drives will depend on torque converter stall and final diff ratio (assuming auto).

What year is it?
Early (pre-72 ones) had relativley high compression but should still run OK on 95 - just don't put too much timing advance into it, try 6 degrerd for a start.
