Hey all, I've made a few things for building Y block exhaust. If anyone has any thing they would like drawn up to print at home let me know. Here a link to my thinkiverse with the files. These could be used as block off plates for engine storage or with a little common sense, back purge fixtures for welding up headers like I'm doing.

If anyone has anything else, fell free to add you links here to help others in the future.
