The Buick V-8 performance experts are:

I do recall Buick offered for a year or two (1964?) aluminium heads
and possibly an aluminum intake 4-barrel intake on the 300.

It is also possible that there might be some parts interchange with
the 340 and 350 Buick V8's, TA Performance would know.

If your existing intake & exhaust manifolds watch up with 340/350
heads that would be your best bang-for-the buck power upgrade,
find a decent 340/350 and r & r the 300.
