cleaning up the slant six head

You guys have got to stop using code, Im sure Im not the only one that would like to know what RRR means and after reading it a few times would take a guess that OAL would mean overall length but just a guess.

Not everyone knows how to make text messages

RRR is RustyRatRod, "Rob", on this forum, he used the 318 valves in a slant head ,1.78/1.5, but due to them being .100 longer he had these special wedges made to fit between the stands and the shaft to correct the sweep of the rocker.

and yes OAL is over all length
