Just received these today. Stainless steel 36mm intake valves and titanium retainers. Hopefully I'll have these installed along with the new head and Toda cams by next week.

I still want to isolate the Toda cams on the stock head to see what they're worth by themselves on my setup with proper tuning. Then, I would like to introduce the ported head into the mix and see what that gets us. To maximize and build upon the existing mods, I would need to port match the K20A intake manifold (flange side) and comptech race header to the new cylinder head in order to harness its full potential. Ideally, a custom header would need to be designed from scratch for the new head's flow characteristics coupled with the Toda cams. I've decided to work with what I have so that others with the comptech race header can have some reference data should they decide to ever get into the head.

****.... impressive numbers in your sig. I'd like to hear more about this buildup and more motor pics.
