Default ported L92 heads

I'm an engineering student at Univ. Miami and currently one of the projects I'm working on is the L92 head. So far, just by hand polishing the short side radius the head flowed almost 15cfm greater and did not separate until much higher lift, max flow at .750 lift (343 cfm) and this week I will be testing different custom ports on the head. After I have compiled all my data and have finished porting a set of the heads, I will post a detailed report of the entire project.


What I am looking for and have already tried searching for and came up nearly empty handed is other's flow numbers for ported L92 heads. If anyone has flowed the exhaust port, please post these numbers too, as well as what length extension they used.

There's been a couple of sponsors who have done sets that have been getting 360 cfm out of them at .650" I believe.
