Are these good heads how do they compare to the sportman 2. I am looking at the ones form sdpc they have a kit for 900 bucks. The combo would be
350 bored 30
lunati voodoo cam 60102LK 262/268 219/227 .468"/.489" 112/108 Hyd/Hyd 1400-5800
Weiand Stealth duel plane intake and a holley 770cfm carb.

This is what the sdpc kit has
64cc Dart Iron Eagle head kit for small block Chevy. 2.020"/1.600" valve diameter (intake/exhaust).

The SDPC Dart Iron Eagle Head kits includes one pair of Dart Iron Eagle assembled cylinder heads, ARP High Performance Series 170,000 psi head bolts and a pair of Fel-Pro #1003, pre-flattened steel, .041 in. thick, 4.166 in. bore, head gaskets.
