I didn't see you had heads too, but from years past, AFR heads on their own have resulted in sub par performance. Usually what people would do is buy the bare castings and have someone else port and assemble them, but again, this was a long time ago and not sure if it's the same today.

I had a local shop custom grind the cam for me. The cam, with the 1.6s, put me at .575/.581 lift.
The custom grind was the better fit. The old 180cc comp port AFRs I have flow 276@.600. The 503 wasen't making full use of the cylinder heads.
Your elims should be in the 260ish range. The place that flowed mine had a set of 180 elims with them couple years back and they flowed 266/205.

I'd really only care about what numbers it puts down at the track. The last time mine was on the dyno, it put down 322/324 or something like that. It was a dyno day with EFA around '00 or so, whenever Fireball blew up his intake. My Dad put down 37x with his car and the only difference was he had SLP mids and LT4 intake/heads, both having HOT cams. I ran 12.4 and he ran 12.2 at MIR.
Mine never dynoed "high" numbers but that really didn't bother me as much as what it ran on the street and track.

I agree with others, I don't care what it does on the dyno only at the track. I've seen many guys stand around in the pits and brag about the numbers but when they hit the track it's a different story.
I didn't see anywhere that you had bigger injectors, were yours OK when on the dyno?
