The best head for your application would be our KC 195 Signature head. We developed this head to be the best street wedge head in the 195 cc to 210 cc intake port volume range. The head has 17 degree valve angle which stands the valve up straighter in the cylinder and unshrouds it for better flow. The valve angle works fine with most all 20 degree valve relief pistons up to about .700 lift.
Because of the higher short side on these heads which makes the runner longer the 195cc intake port is more like a 180cc intake port on most heads. The 195 head uses a 2.02/1.60 valve with a 5/16 stem. It is the best flowing 2.02/1.60 wedge head from .100 to .600 lift out there right now and makes the most power. We have tested the 195 head against the AFR 205 and others and made more power with it even though it has a smaller runner and valve size. The KC 210 head will make more power than the AFR 225 head and flows better as well with a smalle runner. With these smaller runners you get more torque and throttle response.
One reason you do not see more being used is because you have to get them from Brodix or Keith Craft and a lot of engine builders are not dealers with Brodix or do not want to call us or have our head on their engine.
We are about done with a newer larger version that will be for large cubic inch small blocks or race engines that will still use a stud mount rocker. Most heads that flow what this new does has to have a special higher dollar shaft rocker system. We wanted to create a head that a customer could change to without high dollar rockers and off-set lifters. The new head will use either a 2.100 or 2.125 intake valve and a 1.60 exhaust valve. The head will flow 360cfms on the intake and 250 cfms on the exhaust at .750 lift.
Just a little information on some of the other stuff that is out there right now. We do sell a lot of the AFR heads as well which we also do complete in house. We try to get the best head for the customers needs. We have several CNC porting programs for most all makes of heads and this allows us to get the best head for your application. We even have several CNC chamber designs depending on how you will use the heads and what compression you need or want.

Thanks, Keith Craft
