Well, this is probably a dumb question, but are EA71 & EA81 head gaskets compatible? Same cylinder bore.

I dug around USMB & the interwebs a bit & didn't find a conclusive answer. No access to parts pdf's right now. Presumably they have different Subaru part numbers.

They are different. I have had the gaskets and heads next to each other to compare them before.

Well shucks. Thanks turbo. The reason I ask is that a few Ishino ones are left @ autopartswarehouse for $8.95ea.

You can get them from rock auto really cheap too. The ea71 head gaskets from fel-pro are $8.70 each on close out and the fel-pro ea81 head gaskets are $12.45 on regular inventory.
