A friend picked up a 01 Legacy at a pretty good price. It's leaking oil on the HG so he's going to replace them. He asked if there was a better Improved HG. I said I'd stay with Subaru HG's.

Anyone know any different?

Any other hints for a quality HG job on a 01 2.5?

Thanks Larry

I use stock gaskets but do not trust the coatings on them i coat every one with avionic form a gasket every time to insulate the gasket from the heat and oil and coolant thiss seems to holdup have cars with 300000kms on them after headjob and no leaks small step but makes a difference over a 100 headgasket jobs thiss year and no combacks

do y'all know the part number of the 2.5 turbo gasket? is it thicker and does it mess with the compression ratio?

I listed the part number a few posts up. The sti gasket is 0.5mm thick vs 0.75mm. So you get a very slight compression bump and gain probably 1-2hp.

The difference is negligible, but it's a much better gasket.
