Torque Converter Bolts

Sometimes a 5/8" bolt is too long. I had some from (mancini?) once and they would bottom just a bit too soon. I also use the 10230 plate on a PTC (and have used it on other converters) and the ARP kit is just right. I also like the ARP bolts for the thin-profile heads....as you know on the 727/B-RB space is already tight.
Sounds like the ATI bolts might be made a little longer for use with their washers, if space permits.
You can thread a bolt into your converter, snug it, and see exactly how much depth is there..but really the depth that the ARP gets is plenty.
