Now what! I had ordered a set of ARP head studs for my Spitfire (1500) some time ago and just got my head back from the machine shop today so went to install the head tonight. I now discover that the ARP studs are too short! My original studs had 6 studs of a certain length plus two studs that are about 1/8 inch longer to go where the engine lift bracket goes. All of these ARP studs are about 1/8 inch shorter than the regular studs and 1/4 inch shorter than the longer studs.
When I screw the studs all the way into the block and put the head on, there isn't enough thread sticking above the head to allow the ARP head nuts to screw all the way onto the studs! I'm assuming that I need to have the studs screwed all the way into the block? Has anyone had experience with ARP studs on the Spitfire 1500 engine? Is this common, or do I have the wrong studs?
