X head Flow Numbers

you can look at the stan weiss site
x flow a LITTLE better but not much
watch the intake/ ex difference / ratio &all the other details like exhaust

They do not need much lift sometimes more flows less
so the temptation is to go fore more duration
which works up to a point
but you start to lose low end and the heads limit top end
so the super stock cam can make power but is not streetable
so get a cam that opens quick, goes to moderate lift, stays then (bjg nose- rolled over nose)
then closes quick
