I did the forbidden swap. No, not the LS LOL
This block I had shaved to get the pistons at .010 below deck, and I'm using .028 gasket set. The heads are not shaved at all yet. I also wanted my adjusters up high to keep my fulcrum and contact points in line for best geometry I'm going to get short of a kit from b3.
All said and done and I end up using intake side pushrods from the 6.1 Gen 3 hemi. Fits like a glove.
The rocker shaft I left hollow because I could not find a downside to having them filled up, just consider it some reserve oil in the system.
