Re:homemade manifold might be warped, what should I do??
 

A little bit late on the advice, but next time you do the custom setup, it's nice to have a junker head around to bolt the thing to when doing your final welds, that way the heat won't warp it. Tack welds really don't hurt it as bad, but when you start pouring a bunch of wire into the bitch all in a short time period, the heat will ---- it up.

Nice that you have the machine shop hookups, wish i did.
