I talked to him on the phone the other day, and he does not make them anymore. He never got enough volume, he said he either lost money or at best broke even. I would of ordered these if they were available, but I ordered Revolutions instead.

He said he gets calls everyonce and awhile from people who had these things for 20 years and they still are in use.

Talked with him for awhile about boats and motors. He said on a stock merc 350, the headers only gained 10-15 HP, and weren't worth it. But with mods they really opened it up, especially if cammed right. see comparison on 2nd Link. He said the heads were 487X ported, but not too wildly.
They are 26" primaries, 8" collector.

Even though it is too late for me, if he got enough calls or hooked up with a good distributor he might get back into it. He said he'd like to if it was somewhat worth his while.
