they sure look cool, but I was looking at the dyno chart for their "well known head" comparison and wondering who's well known heads they were using to compare. The current crop of "well known head" manufacturers would probably compare favorably?
I'm not knocking them - just wondering because 475 out of an LT1 cammed 350 is impressive, but I think there are much more cost effective and simpler offerings available. L92's come to mind.
As long as you are bench racing them, er, designing, get some plexi valve covers too. :P
just funnin man. Merry Christmas.
/edit - maybe Squirrel has it in his archives, but I vaguely remember an article many moons ago for Dominion heads in HRM. Or somebodies 3 valves. I can't find either, and am having big time CRS this morning.
Jim Feuling's three valve BBC heads may be what you are thinking of. Feuling passed away but was embroiled in a big lawsuit with Mercedes-Benz over tgem I believe.
Spidey, guy hold Bonneville records with Frontenac headed I4 engines from Model Ts and As....I'd take it with a grain of salt. But at the end of the day it is your money, not mine!
Hint is The heads are a raw casting that i get from dart 100% raw and completely machine in house.
Kinda resembles a dart 360 head
Does this mean a Dart 360 head could be made to make this kind of power.
You can learn a lot of other stuff in this post ( Look at the headers)

A 4-valve head must have some potential though. I seem to be suprised by the power out put in mulit-valve heads, but I guess that's in smaller displacement engines.
Steve Harker told me he has a couple McGee quad cams back home and if he had the time, would love to work with them again.
At $6k for a sbc head though?? I could by a ready to go set Brad -6's.
On a Turbo or Blower head I would be looking at exhaust valve cooling more than much else, The valves are not a restriction its under pressure remember.
