Dusty,
Thanks for posting the combustion burn picture along with the explanation of
what AFR did to accomplish this. I have a set of the early AFR190 Street heads,
the combustion chambers shown in your article is a much improved design.
It would be great if Tony Mamo would decide to join the forum and discuss such
features of his superior products.
The picture below is form a 5.3L Truck engine. The burn pattern shows
incomplete combustion with a modern cylinder head. Tony's hard work (and
your tuning) payed off with a much better burn for the improved efficiencies
we all strive for.
