Bought some of those two weeks ago,they are small block.
Interesting - received one set of points today. Look OK but the spring ends seem to long and extend past the screw securing in the slots.
They can be made to work but suspect may not be right - not sure. See what the others look like when I receive them.

Huh? One spring especially if the light one moves to full advance earlier. 2 Springs would slow down the advance right? Springs keep the weights from pivoting out and rotating the cam stop in the advance direction.Watch those springs if you put both in it slams to full advance really quickly. Try one first with the lighter original spring. Blue streak are usually great points.
Nice have to love them!Finally got around to stabbing my rebuilt DP Prestolite distributor in the GTX yesterday and it's doing it's job. Looks like cam stop is allowing about 22 crank degrees advance so set timing at 14 with my dial back timing light. Much better unit than the rebuilt aluminum distributor that dropped 2 degrees dwell when ever the throttle was suddenly opened and vacuum advance came out. This thing has rock solid dwell no matter what you do with the throttle. All this won't matter much on my stock 440 but it reminds me what a quality distributor these Prestolite distributors were.
