Default heads on the wrong side?? help! haha

Yeah, I took all my brackets off, how do I know which head goes on which side? everything is identical, every port, everything. Does it even matter? they both have the same ACC holes front and rear, so it doesnt seem to matter. Anyone know? Please let me know asap, im assembling it right now.

Not if they are new heads. Both those holes will be empty, you choose which one you want on which side and put the plug and sensor in accordingly.

Yeah make sure you swap out the temp sensor and the allen plug on both heads BEFORE you button everything down. It's a really PITA to get them down tight afterwards.

**** the first time i did a new set of heads I put the temp sensor plug in but didnt plug up the other side and after I got the motor warm I see a constant large flow of coolant shooting out the bottom of the engine bay. I was like oh ***, what did I do. I just forgot to plug up the other side, I was so scared I broke something,

I wound up inserting the plug with the motor installed, which was kinda a PITA.
