with a bunch of fab work you might be able to have a notch in the plug and instead of having the intake close at 40 and 80, maybe its like 40 and 60?
or forget that, maybe you pick a good closing time (50-60) and have a port runner that's close to stock T2 but slightly larger?

The reason i'm wondering if it could be done is because i don't have a intake with working 5/6 ports. And i'm going to rebuild my 6port engine as soon as the semi pp goes in the car.
Would be great if there was a way to get the engine ported to suit a non variable intake better.

The aux ports in our engines are just flat-bottomed machined holes that flow absolutely horribly, and if you port them to not have a large reverse lip, you end up with closing timing around 85degABDC. Far too late to make any power anywhere.
Now I wonder. It seems like all of the bridge ported 6 port success stories come out of Europe. I bet your aux ports look a lot better than ours do.
