Hi folks, I've been looking over my setup (1296, billet crank, head work, 2
SUs etc) and I'm wondering about a header change. I currently have one of
the Stahl headers from Joe Siam but I was wondering if I'd gain some power
(high end) with a 2 into 1 style, taking advantage of the scavenging.  I
have one now in the parts bin, 1 5/8" diameter that I only need to weld a
bung on for the AFR probe. I've used it in the past with an engine (SCCA
legal) without this level of prep so I'm not sure it's up to the task.

My Stahl header needs the engine out (current condition) to be removed so
it seems like a good time to try it but I'd hate to take a step backwards
and have to pull the engine to put the Stahl back in.

Any thoughts on this?

thanks
mike h
