In our last story, you saw how IAG Performance assembled our short block with meticulous care. Now our engine travels to the second of IAG’s two cleanrooms for final assembly.
Our half-inch ARP studs are laid out on the bench. Note that these are an IAG design with the proper end shape to fully bottom out in the blind case hole. This is the best way to make studs and not too many on the market have this feature.
Assembly lube is applied to the case side threads.
The head dowel pins are tapped in place and the studs on the 4 outer corners are started by hand.
The studs are run down with an electric impact.
The two inner studs are started on the head gasket.
