TodFitch Posted May 22, 2019 Report Posted May 22, 2019 Just noticed this thread on the AACA web site: https://forums.aaca.org/topic/327261-high-compression-head-for-28-std-six/ The car owner wanted a higher compression head but wanted to be able to return the car to totally stock in the future. So that ruled out milling the original head. If I read the follow on correctly, he did the milling on an old non-CNC machine so I guess he is pretty talented. 1 Quote

greg g Posted May 22, 2019 Report Posted May 22, 2019 As for the triangular cuts made into the combustion chamber look up an engineer named Samander Singh. His theory of groved combustion Chambers was and likely still is a common modification in single cylinder 4 stroke flatheads use in mic rod and go cart racing. Can't tell from the installed pic but I am thinking this is a rwo piece construction necessitating another gasket for the cooling passage npassage piece to connect to the combustion piece. Quote
