I just bought a 2006 Rmz 450 and I take it out for a ride and their is oil leaking out of the cylinder head so I take the head apart to find that the head bolts are not stock and heli-coiled to fit the smaller bolt! So I get the bolts out and take the cam cap out and then I purchased the original bolts and a new heli coil kit to fit the new bolts but when I put it all back together the intake side bolt is hitting the cam shaft and not allowing it to tighten the gasket down all the way! I purchased new intake cam cap after it cracked and now I just need to know if I need to shorten the bolts so they tighten down all the way or do I have bigger problems?
