If you want to stay with Iron heads, the Vortec heads are really nice and cheap. You will need a "Vortec" style intake manifold. You can also try to S/R Torquer.

Since your vette is a '70, I think you have either one of one of the follwoing:
"186" – 3927186. Another good performance head. They were found on 1969-1970 302 and 350 engines. They had 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes, intake port volume should be 161CC's, exhaust port volume should be 65CC's. These heads have double hump casting marks.
"041" – 3947041, also 3947041X. A good performance head. They were found on 1969-1970 302 and 350 engines. They had either 1.94/1.50" or 2.02/1.60" valves, 64CC combustion chambers, DO have accessory holes, I don't have port volume data for the regular 041, the 041X intake port should be 165CC's, the 041X exhaust port should be 65CC's. These heads have a single somewhat triangular shaped casting mark (slope on the upper left).
