Well. startup did not go as planned. i am going to be honest even if it makes me sound like a bonehead.

when we tried to start it, it was turning over and backfiring trough exhaust, so we checked fuel, spark, and spark timing. all was spot on.
We scratched our heads. then trying turning it over by hand.
when we came up on tdc the valves where not closed... we turned it another 360 crank degrees and valves where not closed there either.

So valve event timing must have been of. i degreed in the cam 3 times to absolutley sure it matched the camcard. but i had an issue with 0 endplay on the new cam. I had to order a new thinner camplate from nitemare, a 0.118 pro plate.
Since i live in eurpoe this takes about 14 days.
In the meantime i flipped the engine upside down on the engine stand, and staring working on oilpump, and a new viton BOP 2-pice rear mainseal.

Eventually the the camplate came in i pulled of the timingset , set it aside, mounted the new plate and checked endplay, it was spot on. i must have put the timingset 180 degrees off with the engine upside down. To my somewhat defence i have been working 8 hours on my dayjob, when that ends i drive home, do not shut the car off i run in change to work clothes and drive straigth to the shop, sometimes not eating for 10 hours, pulling 10-14 hour days, at the end i am so whoozey i can't think straigth.

So when we pulled the timing cover back up we found this:

timing marks lined up, but keyway about 180 degrees off. i was nervous i had bendt the valves. so i removed no.1 sparkplug put a boroscope in and turned the engine 2x times over and we could not even see the valve anywhere close to the piston near tdc.

Everything is now corrected. put back together, and it fired up, sounds real good. But i can not drive it out of the shop yet beacuse the shipping company have put about 30-40 pallets just inside the loadingbay gate.

As a result of me burning the candle in both ends for about 1 1/2 month i have come down with the flu and are taking the weekend off, but in the end i am relived nothing was damaged or broken.
