So it may seem like a deal. Better plan on spending another $1500+ for
1. Porting that is an absolute must (unless you want peformance lower than factory iron heads offer)
2. Valves and valve job
3. Rocker stands
4. Miscellaneous machine work to correct various issues
5. Offset intake rockers
We have built a set of those, in the end you will wish you would have went a different route!
But the reputation Indy has combined with the reputation the MP Stage 6 has I think most people would know to pass
