While I'm no expert, from reading all the books, the difference between
a slightly warmed engine and a FAST engine is the head (for a 1275).
Unfortunately, there is also a big price difference between a valve job
and a head from APT.
So without spending a bunch of money, your plan sounds reasonable.
Maybe add an LCB. The next step up would require work and skill, not
much cash. Modify the carbs, intake manifold, head ports and combustion
chamber as per the Vizard book.

done head.
