The headers with -1 heads on the low deck should sit in almost the same place as the EZ heads on the RB block. Looks nice Randy, hope it runs good for you!
I can always upgrade later....Been really happy with the performance of this mild wedge so far. Doesn't flow anything like Hemi heads, but it stays together, and just works in a stock block.
My next build, I want to do a 383/496 from 440Source with the light weight crank again, and an F1R on pump gas...
