I am building my first engine for my 67 camaro, 3:73 rear gear, 700r4 tranny. I have been looking at afr 180,195 street heads, and dart pro1 180's. Can anyone provide me with opinions on what heads to purchase and what kind of numbers my setup will produce? Ideally, I would like 430+hp, 400+lbs ft. I just have the short block built so I can swap out the cam if needbe. Thanks.

350 4 bolt main heavy block (zero deck)
forged flat top pistons (coated) L2256F .040
Bhj balancer
Edelbrock 7501 Performer RPM Air-Gap Intake
Crane Gold 1.5 7/16 Rocker arms
Holley 4779 750 cfm dp carb
5.7 length press pin scat rods with wav loc bolts
3.48 stroke cross drilled w/4 lightning holes cast steel scat crank
hamburger oil pan with built in windage tray
comp cam 3100 timing set
comp cam 292h .501 lift, (need 3000 stall), gears, 2500-6500 rpm, rough idle
sealed power moly rings
clearances: rods: 2.25, rings: .019, cylinders 4.041 to 4.0415 (2 to 2.5 piston), mains: (1)2.7, (2)2, (3)2.7, (4)4, (5)3

I would go with 180's you don't want over head the motor.AFR's or Brodix make great heads.

Personally, I would not use the AFR 180's for pretty much anything. Not that they are a horriable design, but the 195 is vasly superior, and the small runner heads to have are based on the L31 Vortec design.

The 195's will serve you quite well on this motor.
That cam design is pretty dated, I would reccomend going to something with a newer profile.
I reccomend the Crower 00244 (http://www.crower.com/misc/cam_spec/cam_finder.php?part_num=00244&x=0&y=0) or 00245 (http://www.crower.com/misc/cam_spec/cam_finder.php?part_num=00245&x=0&y=0)
They are much more modern grinds, with a dual pattern to compensate for Chevy's inherrently poor exhaust flow
