95.5 tacos too. At least my friend had the HG on his 95.5 taco replaced through the recall - only to have it fail again after he sold the truck to another friend.

 

I just replaced the head gaskets on a 96 runner auto for a friend. 160 on the clock but can't be sure its the original odometer. It failed at cyl 1

 

Just attempting to build a database of blown head gaskets for the 3.4 5VZ V-6 engine. Please copy and paste this questionnaire into your reply post.

When I checked, the heads were flat as could be, no machining neccesary, all valve clearances were within specs. I used Felpro MLS gaskets and have used it for towing this summer, so far,so good. If you are tore down this far, do yourself a favor and replace the starter contacts.
