What can one do to a pair of stock 2.0L heads to improve power, reliability, longevity and all that? I am thinking about 50,000 miles in the future, but I want to gather idea's now. The car is stock injection. Who would you send them to, porting and polishing, inlarged intakes...? Ideas (IMG:style_emoticons/default/beer.gif)

Chris, locally there is Jerry at NWCS who does good work on heads. You can port and polish them to a degree mostly working on the exhaust port carefully. Match port the intakes to the manifolds. Jake Raby likes to weld up the plug holes so you can install the smaller plugs to avoid the cracks across the plug hole to the intake/exhaust seats.
There are several other companies in California that do this work on heads. Depends on how much you want to spend and how much hp you want....
Staying with the stock Djet limits your choices mostly because of the mild cam not the 2.0l 914 heads.

That pic scares me. Somebody pulled some material off that head big time. I find it interesting how he staked the seats.

Took some material off the journal end. Chevy journals, for when I get the crank...

H beams for the deal. Got them balanced, rebuilt, lightened, and rebushed for 22 mm pins for 400. Its kinda turning into a track/street car.

Like the back of my hand, dude! Hoki's is another good spot and the Triangle is always good to pick up women plus the Redhook Alehouse is nice late on a Friday.

Is Mark Stephens still in business? Heard he did good 2.0 big valve heads?

I'm in Michigan and have a pair of 2.0 heads that need to be rebuilt. No major hp planned, just a minor bump and a desire for reliablity.

Any suggestions?

Mark Stephens is long gone. I heard some bad things about his stuff, but it's all second hand so I don't know for sure. But that doesn't matter, he's gone.

Rimco and Audirac do T4 head work, both are in California. Don't know the sites off hand but you can find them with a simple web search or someone will chime in. I do head work but I doubt if you want to send them to Canada, (didn't think so, lol).

When it comes to heads don't cheap out, go with someone that does VW/Porsche all the time and pay to have them done right.

Simply not needed...everyone has their own ways of doing things.
I have not had a dropped seat since 1997. That was 250 engines ago.

The main key is the seat material, combined with the interferance fit.

Like I said, to each his own....
