Oversized valves: good or bad?

One thing everyone just have to keep in mind - the stock induction , head and exhaust system was designed for the 170cid slant when they stroked it to 225 they changed the jetting and that was about it
the 1.7/1.44 inch valve sets is what the 225 needs to breathe if you combine it with a decent valve angle job, bowl blending and gasket matching job.
An take it from me - if you match up the inlet - 2bbl minimum, and sort out the exhaust clean up the stock manifold - that combo with the same cam and cr is worth 30bhp and 35lbft
