2 sets of heads for sb. can you help?

ok, fisrt set says 360 on them, under the valve cover. and the last three digits is 974. what are these off of? thay look to have 202 valves.

second set last three digits are 302.

are these the swirl port heads? both sets have been magnufluxed and checked for cracks, but then sat in a shed for 2 years. any worth to either set? and what is a fair price to ask for these. i am not looking to make much off of them, but maybe more less help out another member
