Hi Ken,

If your 22A seal blocks are similar to the 14-L, I have some instructions that I made up for Phil for removing and installing the seal blocks that I made for him and will email them up your way...You may want to talk with your machinist as it is quite involved making up the adapter blocks for the Chevy two piece seals. ...He may need the engine for measuring and test fitting....Irreguardless, you may wish to remove your seal blocks and go from there.

Where Are You From? Leavenworth, WA / Yuma, AZ
