Yeah we already check it as flat. We stitched it on as to prevent any warping, im actually quite happy with how the welds turned out. The head should be back soon. We actually tested the stock springs and they were 81psi close so were leaving them on there. Its getting all new intake valves the stock ones were severely pitted and wore down in the centers. I decided not to go bigger since I do not want to mess with grinding a relief.
