Head castings A – 2402286, 2406518, 2406518M
B 2806762, 2780915, 4532287 SS only
From the guide- 1962 Chrysler 361.. I'm interested in "B". The 3 heads listed are for SS only or just the last one?

BTW,
This won't answer your question but sometimes those #'s are the actual OEM part number of the cylinder head. I was surprised when I ordered new 083 castings and this 10159552 was on my bill. Turns out it's one of the numbers in the guide

2402286 is a '62 413 Stage I Max Wedge
2406518 is a '64 426 Stage III Max Wedge
2780915 is a '67 440 HP (GTX)

In an attempt to answer your question, after reading Frank's response, I'd say all three are SS only, seeing the HP in much higher than Stock.

287 is a mopar performance head and eligible for SS only, the rest should be good in stock.
