The only thing permanent is change
For as long as most of us can remember, the U.S. automobile business has had cycles. Whenever there was a down cycle, you knew you had to hang in there, and before long, things would come back to normal. And then you would see the cycle head upward again. It's not going to be that simple this time Keith Crain is publisher and editorial director of Automotive News. ...

Kerry's Camaro PDF Print E-mail
This will be a good test because the engine has been running for two years with ported heads. The grooves are the only change made.

The squish clearance will also remain the same as before the grooves were cut. The block was zero decked when the engine was built. The same thickness (0.040") head gasket will be used. 

Kerry races a 80's model Camaro with a mild flat top 355 and a flat tappet cam. The engine has been running great; times in 11.0's at 122 mph.



A broken rocker arm stud prompted a rebuild. Kerry's only complant is the oil gets black after 20 runs. He heard about the grooves and asked if they would help.


The burn pattern was good but ended about 1/2" before the bore on the opposite side of the plug. I believe this is the area where conditions for combustion are unfavorable resulting in unburned fuel passing the rings. With the grooves this problem should be eliminated. The fluid flow during combustion created by the groove will initiate more heat during the early stages of combustion. The resulting faster hotter flame combined with mixture motion in the squish region will create a condition that is favorable for combustion all the way to the bore on the opposite side from the plug. This will eliminate the raw fuel that is being blown past the rings.

I ported the heads when the engine was first built, during the rebuild the ports and chambers were cleaned with a sandpaper roll and the grooves were cut.
