I've got some experience and some research that should help. Either
start at http://www.n56ml.com/n891jf/ and look at the VW links, or go to
http://www.n56ml.com/n891jf/vw/ directly for some head info. Also, see
http://www.n56ml.com/n891jf/2180/ for a thorough 2180 rebuild.
Unfortunately I've never bothered to add commentary to this particular
page, but you can get a pretty good education just looking at the
hundreds of detailed photos.
But to answer your basic question, after being told by countless people
that Revmaster makes the best heads, I finally bought some and have had
zero problems. The valves barely (if at all) need adjusting every 25
hours, unlike all the other heads I've tried, all showed real valve
recession into the seat, due to seat, valve, or both wearing
excessively. Revmaster valves often simply don't change....they're just
like they were 25 hours ago. I resisted the Revmasters because I
consider the dual plug arrangement to to be a hoaky solution (sending a
plug wire through the valve cover), so my answer was to buy the regular
"automotove" heads with single plugs, and simply stick with the single
Compu-Fire ignition system that Jim Faughn had been flying with. I've
had that same system on my '74 Karmann Ghia for 40 years, and it's still
running flawlessly....triggered by old reliable Bosch 009 distributor.
I'd rather have one reliable ignition system than two flaky ones.
I also did a lot of cam research, in search of the highest lift,
shortest duration "tree climbing" cam out there. Unfortunately, I can't
immediately find the one I settled on, but I have it somewhere and will
see if I can locate it today. It came from the very comprehensive list
at http://www.phnet.fi/public/hefor1/eng/vwinfoca.htm , and the result
was a very strong running 2180 VW at our low RPM range. I'm thinking it
was an Eagle 2280 from CB Performance, which may be exactly the cam you
are referring to. I'll send the cam info separately (too large to post,
and I don't have time to post to my website at the moment. Use stock
strength valve springs. There's no point in wasting energy and
increasing valve train wear with anything stronger than stock springs.
I've also found the VW 94mm pistons and cylinders to work fine on the
Corvair, but the Corvair doesn't have the cooling issues that the VW
heads seems to have, so I stuck with the 92's on the 2180 VW.
