They look damn close.   I'll have to take a look at my manifold this weekend and compare.  I think the port between 1 and 2  is for the thermostat. Right? As long as I can make them match up it'll be fine!   I got a friend that can weld anything, he is the welding instructor at the college!  Might have to swing by his place this weekend too.

Thanks for all the info te51levin!!
