... in addition to Ti, Tony Lum is one of the experts on the older engines
... not so sure he's subbed to this list ... but if you get in touch with

I've got heads from my urq (solid) and 5kCSQ (hydraulic) sitting on the
bench in the garage ... both turbos though ... when I have a chance I'll sit
them next to each other to see ... the thing I can't do is compare the block
Ti ... I've got a pile of literature from Tom Nas for you ... had it since
he picked up the Fox last year ... been wanting to get in touch with you to
see if you wanted to meet to hand it off ... perhaps another opportunity for
a Kal's GTG? Let me know your schedule if you're interested.
I'm not sure if Daryn is on this list ... got a couple things for him too
