Doug - Bare aluminum is an answer I'm getting from many. Makes sense. Thanks. Jeff
: I doubt they were pressed in once the

: I believe the tubes were just pressed
: in bare aluminum with perhaps some form

: Okay. This may be a tough question.
: there any original 67-68 Mk1 owners out
: there who can confirm the color (if
: any) of the exposed pushrod tubes? I
: put a magnet to them and determined
: they are aluminum. While Thomason in
: his Guide to Originality says they were
: not painted black like the rest of th
: engine, he says no more. My guess is
: unpainted, untreated aluminum. The
: were likely pressed in once the head
: was installed? Thanks, Jeff
