Thomas,
We seem to be covering this ground a lot lately!
Basically, the peanut chambered heads resist detonation better than open
chamebered heads, and have good potential for port work. They are not rare
(unless you find one with a 219 cast on the front cover, SSS head) but they
are good. If you stick a 39cc peanut head (W53) onto a bog standard L20b
bottom end you'll get compression raised from 8.5:1 to 9.3:1 which will give
the motor a bit more punch but use decent fuel (not LRP shite) watch for
detonation and keep the ignition advance sensible.
The only other thing to watch for is the condition of your rings. If
they're worn then raising the compression could make the motor blow oil
smoke.
Good luck
- Tom

Subject: what carby? and W53 head.
Pulled a 175 CD stromberg off a dumped volvo today. Is this a good/useful
carb? Also-I just realised the other day that I have 2 W53 heads. One is off
an L16 from a stanza sss I found dumped in the bush a while ago, the other
is on an L16 in the shed. The head from the stanza has peanut combustion
chambers and ~31mm intake ports. The other head looks like it has had some
DIY enlarging of the intake ports done to it. Are these rare heads? will
they make a standard engine go harder? can I bolt one onto an L20b to make
it go harder? Thanks,
Thomas.
