Honing with 4stones intead of 2

Over the last 5 years of building race engines i've always used the standard 2 stone/2 shoes honing. Has anyone or does anyone use 4 stones and if so, does it make for a rounder cylinder. as i plate hone all my blocks i always measure the typical 12 and 6o'clock positions, and also 3 and 9. the cylinder (to the best of my dial bore guaging ability) appears to be round. Does it keep the cylinder a little cooler when honing?

I've tried the 4 stone set up (just for S&G's) there are 2 things that will cause a problem, first most of the portable hone heads wont allow for you to use 4 stones (there is diferent stud spacing for the stones and wipers) Also the wipers are used to brush away honing debry and distribute honing oil in the cylinder.

I am aware of the other honing heads as that is the type i currently used. i have used sunnen ck-10 many of times at SAM and working at another race shop. i'm not complaining of my results nor do i have problems w/ring seating. just wondering what other guys are doing.

I see sunnen uses 4 stones for there new diamond tooling and new
SV 10 honing machine. I have used Ck 10, Cv 616 both with conventional 2 stones and 2 guides. But nothing in my experience compares to CK-21 and 8 diamond stones in terms of getting a cylinder straight. It's much harder to correct an already ran engine that has cylinders out of round using a conventional 2 stone silicon carbide hone head, compared to using diamonds and Ck 21.
