GMPD catalog is the easiest method. It shows the crossreferences for other applications. Things to look at are mostly engine internals that may be unique to the L27. Rods, pistons, wrist pins, bushings, bearings, balance shafts, timing sets, valvetrain parts, etc.
So far, the ONLY valvetrain part I've found to be in this category is the pushrods. Before panic sets in, they ARE available from many other sources, but you have to know your specs to find them.

I'd prefer another source. S1Perf hasn't even updated their website to show something other than 'coming soon'.
I'd like an OEM trusted source or name-brand aftermarket that'* confirmed. In the long run, I'll probably buy two full sets from vintage.
