Following. I have a 2000 3.6L 5 speed with a blown head gasket also. Just shy of 200k miles. Ordering Harland Sharp 1.7 roller rockers for sure. I don't know if I should replace the lifters while I'm that deep into the top end or not. Suggestions for any other performance adds to do while I'm at it would be appreciated! Cam? Throttle Body? Etc.
You may not have a blown head gasket unless your engine is overheating. The intake plenum on the V6 Magnums have a bad habit of warping. Sludge also builds up in the oil pan and clogs the pickup (only when oil is hot) so your pressure will drop to 0 until the oil cools down. Go to the following site and purchase the upgraded plenum pan and also the modified throttle body for better air flow. These engines are great for low end torque but suck on top end.
