That was me. ;-)

I'm not familiar with your vendor (you don't mention who), and my experience
was with Aircooled T1s, which vary a great deal from engine to engine with
the amount of age, whether the heads are stock or aftermarket, whether they
have been decked or not. Lots of variables, and almost all the ads you see
say "Fits all 1300-1600 engines." Which is hard to do considering the head
differences, and still aligning and sealing with heat exchangers and carb
heater tubes.

Well as Ron stated "Most of the extractor type systems, such as the
Bugpacks, Empi's, and Thunderbirds, are of relatively thin metal and in many
cases are crimped rather than welded on the ends." So a little "shaping"
with a mallet, or torch has usually been required to line up with every T1
I've worked on.

And as I said before, this is for aircooled engines. I must plead complete
ignorance concerning wasserboxers (and some other things).
