Vortec Bowtie heads build advice required

[Garry Barlow]

Hi all,
I would appreciate suggestions from the more experienced ( than me ) engine builders on this combination of parts for my re-build. The goal being a high torque daily driver in my 1972 longbed.

Start with a rebuilt Vortec 330 hp short block.

install Bowtie Small port ( Version 2 ) vortec heads. ( max lift 0.530 )
install Comp Cams X4260HR cam 210/214 with 0.474/.474 lift. ( 40 overlap )
install comp 1.6:1 rockers to increase lift to 0.506/0.506
install AFR Titan dual plane DPR composite intake.
install rebuilt & tuned by JET, Quadrajet carb
install 2 1/2 " Corvette rams head exhaust manifold, into a 3 1/2" single outlet. ( looking for a semi stock look. )
install Petronix HEI distributor.
Max compression 9.5 ( for iron heads )
Diff ratio of 3.73 and a 2000 stall.
