Started first crank
Looks great, no noticeable casting defects. Bolt holes machined correctly. Right side center two bolts were a bit challenging to get started. Some relief cuts would be nice,. And that is with the Jegs intake bolt kit. I couldn't imagine using the factory hardware. Motor started first crank, still need some other work before I can drive it but I cant wait.

Really helped performance.
Liked the intake manifold works well. Had to do some clearance on the valve covers to fit around the intake runners even with the thicker valve cover caskets. The product description did talk about it and glade I read this advance.
