Thanks for the kind words, guys! I know some of what I post is probably boring, but I'm still so excited, that even the small stuff thrills me!
We have discussed 3 valves, as it was brought up in a thread on another board. I don't plan on even firing an engine with these heads until after this season is over this year. This will give us plenty of time to get these heads right. One we have good, usable heads, and flow bench numbers, we'll try several different designs.
I hadn't thought of sinking the chamber in the bore, but will bring it up with the team members. I don't feel comfortable spinning the engine above the 6000-6500 rpm range, and we'll do that/ try that, with the long rods (8.75"), and a long stroke(4.625"). This idea may prove to be beneficial- Thanks!
update:
Well, this whole approval process is not going well for me!
The 3-piece head is not an acceptable design, because even though the bottom piece contains part of the chamber, it still acts as an adaptor plate.
So, I have to make a decision here. I can either work around the existing bolt pattern, and run XXO, or make the 3-piece and run time only.
More when I think on this some.
