So with this new port design I'm trying to get some more flow. My question is specifically regarding the transfer ports. On the 660 I always went wider, never messing with height. I'm wondering if transfers can be opened up, height wise, and if that messes with "port timing" in any way raising and lowering the intake/exhaust does. I'm struggling to verbalized my thought but I hope this makes enough sense to get a response. So I'm just wondering generally if I can take the port up and down to increase the charge without worry about port timing in the way that one would worry about it on intake/exhaust.
What's working on the 661? My mod is going to require massive flow increase via the transfers to work and achieve what I'm looking for.
