I'm looking for a pair of the cast World Product S/R Torquer 58cc heads that they made for the 305's. Apparently they stopped producing the S/R Torquers in 58cc a couple years ago.

What is the difference between the regulars and the torquers?
I thought I bought the S/R Torquers 20 years ago when I rebuilt my 305.
It was not until only a few years ago that I found that what I received from
RHS were actually circle track heads with 2.02/1.6 valves in them and some
improperly oversized valve seals that the retainers smacked into at full valve lift.
But at the time I figured that RHS knows more than me and bolted them on.
Cam lobes got destroyed as a result and all that shrapnel went through the engine,
destroying pretty much everything. I was able to resurrect it, and hope to get the
car back on the road this year.
As far as I know, there were no differences to the head castings themselves.
The differences were in the way the valve train was set up.
The S/R heads are just an improvement in casting over the stock heads. S/R =Stock Replacement with not much difference in flow over stock. The Torquers are designed to flow a bit better than the regular S/R heads or stock heads.
Jegs (e b a y) store has some currently listed. Search for "042650".
305 circle track racers MUST use this head. Good luck.
I'm guessing that first sheet is the current heads. If you look at that second sheet/link they mention the 305 S/R Torquers. Like I said before, they have been discontinued, but they most certainly did them in the past.
