I really would love to see flow results for both, especially the later one with both modes of the resonance flap.

to tell u the truth, i think both heads will surprise us with how good they r. I know the M103 head really flows, as Roman (Pumpsih) can confirm, for it generates serious power on fairly little boost. and the turbo that u think is good for say 350hp on a 2l 4 cyl, will barely have enough puff on an m103 to provide proper topend flow.

I was on the phone with roman few months back asking abt a turbo i wanted to fit on an M103, i recall he told me that the merc heads out of his own experience flow well and will need a large turbo to cover its needs.
