TBI Heads on a 1970 Block Carb'd

[Andrij]

Looking to put the old TBI Heads on a 1970 Block, I bought it smoking with 305 heads & while apart thought I'd put on better heads.
14102193 65cc TBI 1.94 intakes and 1.50 exaust
GM 391467 350 small block
Thinking of a dual plane intake with a Holley carb
Been looking around the forum, & I'm flooded with carb to TBI computer stuff, to TBI to VORTEC, & though having 906s, planning to stick with TBI since my light foot seldom goes over 2000 RPM.
Seeing if anyone has any advice for a cam, picking a gasket, or anything else you'd like to impart. Thank you.
