79 scorpion cuyuna model?

[sx-elerator]

i have a 79 scorpion sting 440, it has a cuyuna 429cc, pull start, air cooled, and last winter the clutch side piston got burnt. so now i'm having it bored .030 over. but i can't find a model number to order pistons and a gasket set because part of the engine tag is missing. any help would be appreciated
