I just installed a set of iron heads with studs on a stock block . and I don't remember the outside studs threads being that much over the bolt compared the the two inside studs when I tore down the engine . see pic . yes all studs are hand tight into the block with sealer . and obviously the longer studs are on the inside . I know it's most likely fine just seems odd and it's bothering me . anyone have a engine on the stand with heads/studs they can take a quick look at ? thanks .
