[Spridgets] 1275 exhaust valve emissions plugs

[Philip Nase]

I'm about to start assembling my first engine (with some adult guidance).  The
head has the old emissions fittings simply pinched closed.  I'm looking for an
alternative solution realizing I should keep the interior fittings as is.
What is the solution?

I'm also looking for information on what tolerances are acceptable and what to
measure on rods and crank. If anyone can point me to publications or online
information showing me it would be really helpful.

Everything except the 20 over bores is standard.

Thanks.
