go with your gut - if something feels off, it probably is. i've burned myself more than a few times letting my brain tell me to go down a certain path when i had vague misgivings... now that i'm working on my third head, i'm learning that setting the valve geometry is not that complicated - but it's really important.

Seems like one of the reasons that people like to work with Rebello or DatsunSpirit is because the owners share what they know and the customer learns something when it's all done. Your guys seem more like the old, classic, "leave it there and we'll call you when we're done" kind of guys. Guys that always come in at the top end of the quote range and call you with "problems" found requiring more work. I think the descriptive word is sketchy. On notching the block, a general trick that I learned from a machinist is to turn the block upside down. The grinding or filing chips will fall away from the cylinders. That's if you're planning to leave the block assembled.

If the machinist doesn't want to do the work, find someone else. You need and want to notch the bores. Datsun motors aren't the only motors that practiced this notching. I notched my bores right to the limit of the HG fire ring, but you don't need to go that far. If you are careful and take your time you can do this yourself. Just don't go to deep or wide. Sounds like the machine work is all done and you just need better valve seals and a wipe pattern checked? I would think any competant machine shop could do this. I handed my machinist the "how to modify" book for a references. I just told him that I know he doesn't see these motors everyday and just thought he might want the book to look at.

No experience with a 911 but it mounts easily in a 1978 280Z:

Let me start... "I'm announcing a release date for the HellFire Classic of May 15th." Good thing you didn't announce which year. Hahaha!!

I thought about it but didn't. Reading Blue's tips had me thinking that they would work with OE size rotors but I was just wanting to stop reasonably quick. here's his write up, http://atlanticz.ca/zclub/techtips/toyotabrakeupgrade/index.html here's what i bought from chain stores for around $200. Slotted and drilled rotors reman calipers and a can of red paint. Also bought the stainless hoses from the calipers to the hard lines.
