all aluminum engine???

ANY new motor .. aluminum or steel .. you are going to need to check your cylinder head bolts and exhaust manifold bolts after a couple thousand miles. Bolts will vibrate loose and simply need to be tightened. NOT OVER TIGHT.

FWIW, on my iron block/aluminum head FE, my builder's instructions were to NOT torque the heads, torque the intake manifold one time only (after a few hundred miles) and only torque the oil pan, etc. if, and only if, I saw oil leakage around it.

Rickd, is there a spec for how tight these bolts should be? While I do not have my Cobra yet I will soon and am just curious as to what the torque wrench setting should be. tin-man
