Hi iam new to this form frist post. Anyone know what the 18rg cylinder head airflow cfm is. Stock and race spc.What would the cfm be with 45mm inlet valves and 38.5 exe valves stage 3 port egg.With a cam lift of 0.426in 10.8mm 295 duration.

stock cams are 240 degree duration at 50thou lift. and lift is 9mm or so. stock valves are 46/38 i think so not much gain there if any. the porting would be the biggest difference i'd see.. only one way to find out have it gas flowed.
I can have heads flow benched here.. but it's $80us per hr and i'm in da states..
