Thanks for the info. I also needed to know which cylinder is number 1 and how the cyl are numbered. My local carquest parts house provided that info and I"m posting it here in case someone else comes looking for the info.
When viewing the engine from the flywheel end, the number 1 cyl is on the left bank nearest the flywheel and the number 3 cyl is directly behind #1. On the right bank, starting nearest the flywheel are #2 and #4.
