Peak Speed Shop OB?
I don't know. Their website is gone, doesn't look they have a Facebook. Google shows a phone number.
I do know this from a a few years ago.
1) Peak Speed Shop ported an LS6 intake manifold for me. The manifold gained ~1 to 2cfm on the flow bench in my cylinderhead testing. Not much for $400
2) Peak Speed Shop ported an TBSS intake manifold a forum member. It had good gains on the flow bench. Seemed like the $400 was well spent.
