I was looking online today about quench distance and other things related and ran across Signh grooves. Has anyone ever tried putting them on their heads?
Basically, they put grooves in the head where squish occurs - supposed to cure everything but diabetes, it seems. Take a look at the following links, I found it interesting, anyway:
http://www.herningg.com/singh/
http://www.herningg.com/singh/Engine Running Tests Analysis.pdf
Here is a thread by a guy who builds engines and is really keen on the idea (long thread):
http://www.hotrodders.com/forum/singhs-grooves-ported-milled-vortec-heads-stock-350-a-102958.html
An example of a Singh Grooved head:
I have ran across a few sites where people are swearing by them to fix pinging issues, mostly on the hyper-mileage sites. Seems a little like 'snake oil', but I haven't seen any complaints from people who have tried it (maybe they are to prideful to say they messed up??)...
