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!!
