Hey thanks Carnage! The manifold is 1.5" SCH.10 304ss. It's my first tig welding project. Probably should have done something simpler for noobs like me but so far looks ok. The runners have a calculated length of 30" from valve seat to collector. I used rod cut to length to help me with that. Used the stock cam calculations to measure desired length. They're not 100% equal. Some small compromises were made. But all in all I'm satisfied so far anyway.
