This may be a newbie question, as it's my first time changing heads... But I got some Trick Flow heads (185cc) to replace my stock heads. I was expecting there to be some sort of marking on the heads to denote which end goes to the front of the engine and which goes to the rear... but I don't see anything.
The only noticeable difference that I can see is that on the exhaust port sides, one is marked 76772 while the other is marked 76774. Not sure if those are serial #'s or part numbers. Again, I'm not really sure it makes a difference which head goes on which side of the engine, but I'd like to make sure.
Obviously I could wait for Trick flow to open on monday, but I'd like to finish my project and get it all put back together today. Any help would be appreciated.
