As far as cams...although the Motorsports are good I run a Competition Cams roller. You can call them in Tenn toll free and they will design one specifically around your components and needs. I called them a couple of years ago, told them what I had....heads, pistons, compression ratio, manifold, carb, gearing both tranny and rear, weight of car etc. and then told them what I wanted. I also added that I still wanted good vacuum at idle, but a nasty sounding idle to boot. It took him less than two minutes on his computer to come up with it...and it was beautiful. ..custom ground for me..He set the lobe centers at an odd angle to give the nasty idle, but retain good vacuum and it pulls HARD from 2500 up past 7000. Several weeks ago I called again and had the same guy design one that would pull from idle like a bull moose, but still run good up to 6000....again he did it. The fellow's name is Eric in the tech support sales dept and he can be reached anytime that Comp is open. he ran Pro Stock for years and can tell you anything you ever want to know about cams.
I do have the first cam if you're interested...less than 1200 miles and little if no wear...the specs are..500 lift with 1.6 rockers, 285 intake duration, 291 exhaust duration at 106 intake center line with a 109 lobe separation. It's strong and sounds great.
As far as heads....I run twisted wedge from Trick Flow. I've been very happy with them although if you run more than 540 lift you'll need special flycut pistons to accomodate the twisted valve arrangement. My builder doesn't care for the Edelbrock heads although I'm sure they're fine. The only others I've had experience with are Blue Thunders, but they're price prohibitive.
Hope this helps some..
