MMZ, I thought you would enjoy seeing a half-way point with the plenums... They still need a few edges shaved and grooves ground and then a serious jewlers rouge polish... I've increased the LxW of the port by 3mm W X 5mm L and had the new gaskets made... And it took forever to polish the entire inside... I should have cut them in half then re-welded them...

PS: Where the heck is WOODY ?
