anyone got some flowsheets for 3mm oversize exhaust valve'd heads?? In the spirit of sharing information, here's a flowsheet of a head with a fair bit of port work, but retaining standard valves: And another flow sheet of the same mob further developing the head, with 1mm oversize ex. and in. manley valves you can see gains of ~10% more flow overall on the inlet, and ~15% on the exhaust. I'd love to see how 3mm oversize valves go in the exhaust.... Some original photos have not been recovered yet.
