When changing out a head on a M series do you have to drain the anti freeze? or can I leave it witout making a mess and bleed it after i am done. Also does anybody know is a racing station head the same as an RKT head?

I would drain the antifreeze down a ways. If you don't it will spill into the cylinder and get in your crankcase. Antifreeze and rod bearings do not mix! I know from experience:) If you do get any in there a vacuum with a little hose on the end works good for sucking it out, but you would have to pull the cylinder. Draining the anitfreeze is just alot easier!
