[Tigers] alloy heads on stock 260

[michael king]

I am sure this was covered about 2 years back, but cant find the
thread via searches.

Can you fit alloy heads and roller rockers to a stock 260? I know that
most all the alloys heads seem to have a larger combustion chamber
size, and the block would need to be tapped to fir the web/girdle for
the roller rockers... but are there valve to piston issues, to lower
compression or anything to watch for?

What heads have people used?
