The offey would be your better choice for lowend to Mid range power & torque. As for your compression One of two things can be done. (stock 250 has a 8.5-1 compression) You're looking for a small gain in compression,So you can
mill the head and Zero deck the block.Or you can go with a 194 head which will give more then a 9-1
compression.
As for a cam for what your plains are for that truck I would say stay with a Hyd cam and Look for
something in the rpm range from Off idle to around 5500-6000 rpms and no more then a 530 lift This will still make a fairly good daily driver and a weekend wheeler as you put it.
Daul exhaust headers Or Tom Langdons dual cast exhaust will help out with the exhaust flow and help the motor breath better.
As for the head this is were you are going to tie up some bucks.1900-2200. Some shops even more.
The head needs to flow If it don't then all the money you put into the motor (ie cam ,compression,dual exhaust intake carb so on is
not going to give you much If the head does not flow well)
so in order to get this head to flow your looking
at Port work at min. a good 3 angle valve job and
step up the valve size (in. & ex.) you can also have it lump ported.which will also In crease the Cfm flow of the head even on a stock sized valve.
There are only a few shops around that really know anything about our L6 chevy heads. Most all
machine shops work mainly on V8s or now into only the import stuff.
God doesn't like ugly.
