I was wondering if anyone could tell me the flow number of a stock 6.2 head and a stock 6.5 turbo head and the combustion chamber size of each thanks.

 

cant give you exact numbers right now but i can tell you early 80's 6.2s have bigger valves and with a nice port and polish job can flow a lot. combustion chamber size is kinda hard to give. this is a indirect injection diesel engine. so there is a precombustion chamber called a precup where the fuel is let in. then it mixes with the air in the cylinder
