Hey folks. I put this question to the SVX forum, but since NASIOC has infinitely more experience with this sort of thing...

Doing the head gaskets on the SVX soon and refurbishing the heads while they're off. Found out that Supertech has a valve set for the EG33, SS intake and inconel exhaust (Overkill for an stock engine, I know). Link to Ebay. I've contacted Supertech to confirm the specs on the valves.

The question: These valves are 2mm longer overall than the stockers. Can Subaru hydraulic lash adjusters take up an extra 2mm of valve length?

Your valvetrain will now be an interference setup.
I'm assuming you're taking .020 off the head?

I would call Supertech and ask them if the decking and bigger valves will be a problem.

Realistically, don't waste your money on valves. Get some stock ones, or re use your old ones.
Spend your money on a set of cams!!

(If you need valves in great shape, contact me.)

And to answer, yes, 2mm is not much to take on stock setup.

Cool. So skip the valves, clean and re-use the old ones, save money, buy some cams. Got it.

My spare set of heads will be sent to the machine shop and shaved as needed. I'm not looking to take much off and raise compression though. They'll also be grinding the valve seats (the exhaust seats have some pitting).

.020 is the limit for shaving.

Port those sad heads out...
The runner of a 20k head, with the top of a 22e. Super good combo.

I believe those valves were designed for reduced base-circle cams
