When shopping, are LA & Magnum cylinder head bolts the same?

I see on the ARP site that they list different head bolt sets for LA vs Magnum, and the illustration sure looks like the Magnum has all longer bolts for the uppers, and the LA just has one long bolt and the rest are 'not as long' bolts for the upper row. I cannot recall the length difference between the long and 'not so long' bolts, but it may be that the 'not so long' bolts will 'kinda-sorta' reach through the Magnum heads.

And of course, to confuse things, the Edlebrock Performers take 2 long and 3 'not so long' bolts ......ARP makes another set for that application FWIW.
