I found a set of 3401's in an old stores system. Was bought out by Car Quest but still had some old inventory.
Also, I had a GM dealer check parts stock and found a set of GM's in the system. Probably more out there.
3401's are fiber coated type, GM's are all steel.
I've also used the standard Fel-pro set (I forget the number) that fits 400 and up without issue, you just lose some compression and quench.
