Hello guys. My first post :D
Checked my port durations after i lifted the cylinder 2mm total. 1mm plate and 2 gaskets. and milled the same at the top, sqish is good at 0,5mm
My issue is that i ported the exhoust a bit, and i think too mutch. Lets say 2mm on eatch side and 1.5mm on top. that made the exhoust duration 187° and blowdown 34°. is this way too mutch? my understanding this wont start hit untill 9000rpm with the right pipe. tranfser duration i think is good at 119°..
