Chip,
Are you telling us that there's a typo in the T-Series Handbook? In the
Golden Anniversary Edition, your article, "Back to Basics # 7 -
Ignition" carries the statement "All XPAG heads I have seen or heard
about which bear the number 22592 (I REPEAT 22592) are early heads,
which therefore require 1/2 in reach L-7 plugs." Should that, in fact,
read 22952 as Bob suggests and you seem to confirm?
