edelbrock heads ?

You can "driveway" cut your pistons but not really worth the time imo. You can change them to 1.90's but it pretty pointless when you can just buy the preformer with 1.90's which is more than enough for a mild 302/306 with a power adder (to a point). If you really want 2.02 TW heads will work with stock pistons with no piston to valve up to certain lift (5.42 lift I think).

im not sure yet, but i think their is some used ones i just came across and i think they are 2.02, waiting for the seller to get back to me on that, and if they check out ok theyre cheaper then buyin new ones. ,so whats involved in changing the valve sizes? other then just buying new valves
