Going with QA1 uppers and have question

BBJ 1-59/64
SBJ 1-29/32 (1.809)

note that these are "square" heads, so you *can* squeak by with a standard fractional socket (sometimes!), it's best to use the right tool for the right job.

small upper can be found under American Muscle AMM23456 and the large upper is AMM23457. importantly, these are 1/2" drive units. most other BJ sockets will be 3/4" drive.

i have a proto 6549 L for the small. there are others but you can pick these up on ebay cheap.
