Yep they are shown on our FB page. There's an album dedicated for them just have to s roll through the plethora of albums

Thicker headgaskets could help but then you're changing compression ratios once more. Running too thick a headgasket can have issues as well. I do use Tomei from time to time on the rather large builds but I've since moved to our own hybrid MLS gasket that has a few more features tomei gaskets do not

I forgot to mention too that the floors of the intake ports had been altered previously too and we're dropped A LOT which adds even more obscurity to the ports lining up. Please trust me when I say we did all we could to salvage as much as possible but again in order to make this right to where you'd have very little offset/change the ports would of needed to be welded on the floor, decks rewelded etc. WAY more work and at a significant expense that I know Nick did not want to get involved with. Buying new heads was out of the question too. Just want ppl to know this isn't the norm and we've done a lot to try and get this as best it can be within the confines

I'll try to draw an illustration to validate my statement of sorts however you must understand too that the Engine is not sensitive to airflow being it's forced Induction vs naturally aspirated. Two totally different systems where one does see an affect by minute changes like this where forced Induction it's nowhere near as fussy. FI cares about only 1 thing and 1 thing only....get as much air as fast as possible to the back of the valve. The minor offset shown there will make zero difference in performance. Yes I agree the appeal of what you see in the image doesn't look good to the eye but this is an image taken at a very difficult angle so couple that with the obviousness of what you're looking at it begins to get muddled. I agree though I wish things could look/feel different in a better way but the fact is, is that to fix this correctly which the only way we care to approach issues is to tackle it like I mentioned above.

Around .010-.015" will require phasing of the cams to get them back into spec however don't rule out the grind of the cam because there's no such thing as a perfect cam grind. I've seen other cams the Z32 platform use be out as much as 5* as advertised.

Could but then we kill velocity by making the entry ways considerably larger just to save face of trying to match them. Even factory lowers to the heads don't line up correctly. It's all production tolerances. Only way to do it is right and the right way would have been to essentially replace the deck material then surface accordingly. Believe me it's not favorable but a picture doesn't show everything. It's not off as much as you'd think.

Yes unfortunately but let me clear the air about why it's this way. The heads had been surfaced quite a bit before we got them. In order for us to correct this to how we'd of loved to do is weld the decks of the heads and mill the intake flange faces to get it dead nuts. There's 2 things we have working against us..time and more time. If the heads hadn't been cut so much prior (casting numbers were already milled off) this would of lined up fantastic like our other setups have been.
