Thanks for the info.

I always liked the basic Stage VI design, but the MP finishing wasn't satisfactory. Now Chapman has gotten a great set of castings to port and put things competitive. I just hope the final machined and fitted cost is not prohibitive.

Now we just need a mega block in low deck size for these heads.
