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.

doesnt matter. the heads are symmetrical, they can go on either side

Thanks. They looked symmetrical, but I didn't want to make a mistake and find out something was slightly different. Trick flows instructions show only having coolant ports in the rear, but this has front and rear.

Thanks again.

the head gaskets are directional... if you look at each end, there are passages for coolant, they go towards the back of the block.

if you look on the front of each gasket it says "front" and that NEEDS to go the front of the car, and yes, that means one will be upside down
