Yes, thanks very much for your posts. Really interesting and I'm still incredulous over the results compared to what we are used to in our world. Be interested to hear what you think about the differences the head plays between n/a and forced induction. Anyway, hope you recover asap and can get back into your projects.

Wonder what the limits are on the 16v heads?

Would be interested to know how much more the 2.7 head flows than the std head. Intake ports are larger, so surely it should flow slighly better than a std head, assuming fitting the same 48mm intake valves in both?

Valve seats were provided by the shop that did the work, Goza Auto Machine in Acworth GA.

Not good Slate. Called VTM and phone was redirected to SI. The above was story communicated to me. I bought valves from VTM a little over a year ago and was happy with them. How much heavier were they? Did you discuss the "not true" issue with them?

Planning a High Flow Head 2.0, aka Ultra High Flow 8V Head Hoping to have a really great flowing 8V head (yet low cost) ready for the Spring. Who is using 50mm intake valves?
