Sanderson advised they can do their Limefires (lakes style) in 1.625" primaries, but they come out of the ports at 90* which destroys my splash aprons.
I have a set of stock port 3/8" flanges coming from Stainless Headers Mfg in MN ($60 plus shipping), and I will cheat the tubes back 1/8" from the back, flow the weld in and port the flange width to ease the flow some. Should be OK.
