Steve,
Love to be corrected but I've always assumed the guides are
knocked out only after the head has been evenly heated up to a
particular temp, then new ones set in after another warm up as
required. I would have thought best to let the engineer remove and
replace all the guides as he may be needing to do other follow-on
work with seat cutting etc. Just think he'd prefer to be the one
to do it all.

Greetings all,
?
I'm at work prepping the cylinder head for my engine, with
some carbon cleanup still to do in the exhaust ports but impeded
by the guides. I have new guides in hand and will turn over
those, new valves, spring package and the cleaned up head to a
well regarded local builder. As he's a bit of a journey out of
town I'm contemplating knocking the guides out myself so as to
get the head as tidy as possible before he assembles the lot.
Would a correctly sized punch and hammer be a sensible approach
for this?
?
Cheers
Steve
