<x-charset iso-8859-1>they are not "junk", but they cannot be returned to a quench chamber design.
However, they are enough in demand you can probably get top dollar for them,
especially on ebay.

There are some guys that will use nothing but semi-hemi heads on the upright
engine for street use. I don't use them (I used to) and in fact do some
stuff that's "impossible" and have had great success with it. My latest
projects are 11:1 2443 and BOOST on pump gas (don't laugh, one friend of
mine is 11:1 and 24psi on pump gas), 13.5:1 2332 aspirated on pump gas, and
11:1 1914 on pump gas. I must be doing something right. Don't try this with
flattop pistons!

Also, these engines utilize deck heights in the .020-.030" range. Notice
this is significantly less then the .100"+ that some people are having
detonation problems with, and "solving" by resorting to SH heads. I suppose
there is a benefit to this, if they ran out of fuel they could piss in the
tank to get home. :-D
