Thread: How can you tell the left from the right cylinder head?

1993 heads and i just need to know which is left and which is right. Thank you.

They are interchangeable.

Don

Thank you very much sir.

Depends on the engine---OHCamshaft engines have different heads

On a normal pushrod engine they are same but if you take them off your engine there may be accessory bolt holes or emission or cooling pieces or sensors that are different on r and l heads so you'll want to put them back on the same side
nothing like getting an tight fitting engine back in a car and finding egr passages on the wrong end----

Well the heads came off of an engine that I didn't tear down so I wasn't able to mark which side was which

we still don't know what kind of engine!!!!!!!!

You posted in the Chevy Small Block forum - is that what you have? If so, they're symmetrical.

I saw that's where he posted, so I assume sbc too.

Don

Man--I need to know if it has ps,pb, auto trans/stick, rear end ratio, tire size, what octane fuel and if he has his vacume advance hooked up

No, I just read the posts as they come up, never look at the forum

no not any of that stuff yep like jerry said just a GM pipe plug in the side of a 30 year old chevy head .now the head is on the wrong side for the water sender . soooooooo now it on the wrong side .can,t get the fu k ing plug out to put the sender on the right side now what ?

It is a small block chevy.

Just lay them up side by side and see if they have the same holes in the same places, and ain't nuthin' stuck in one, like Pat said, that ain't in the other. Same-e, same-e; easy.
