I was browsing the web and I came across a website that talked about cutting grooves on the quench surface of your heads. It's supposed to increase turbulence in the chamber for better quench and higher CR's without detonation. Has anyone ever heard of this before? Here's the link to the guy who developed the patent (yeah, it's patented) for it:

Interesting AND my first thoughts reading the "speel" was, "I wonder what it would do to help a flathead??".

He, He!! My flathead B&S lawnmower engine comes to mind!! Sucker might run on kerosine????

Anyway, they put dimples in chambers as well as have made "ramped" pistons so why not try it... New, fast-burn, heart shaped chambers as well as "torque" peanut shaped ones..

BUT I could see that notch being a great place for a crack to start IF it isn't radius'ed right and such.......

I'll try that with a set of junk heads first just to compare. It makes sense but then again so does a lot of stuff I read! I think if you finish the groove of with a fine round needle file it would resist cracking.

Cracking- and plugging up would be the main problems. Why would a groove in the head be any less inclined to clog up than a spark plug? It wouldn't- so I'm thinking if this does work- it might be only temporarily.

Sharp edges create hot spots. Hot spots enhance detonation.
In full tilt race engines I spend lots of time smothing out all burrs and sharp edges. Others use special coatings to acheive the same thing .

something to think about my 2 cents :bowtie:

Never seen this on any factory or aftermarket heads, and I'm real sure they have spent millions to perfect those designs. I'll pass on this mod.
