Use ultra black RTV to seal that factory mess up.
That head gasket should be fine if only torqed down and never ran. For the dyno engines, the same gasket was used for all head changes with never a problem.

Where do you run the oil supply line from the engine to the turbo?

Looks good, only thing that kind of confuses me is if there is a reason you're still running your old fuel system with your new? Seems like you could just go with the new fuel system to me maybe... But I'm not any super expert. Also a blow off valve will help protect your engine big time so may one to look into that investment in the future, and if your all about it sounding awesome blow off valves give a pretty distinct sweet sound. Just my .02 Glad you got it back on the road.

love the build man keep it up this is what i'm working towards!
not to divert but a page or two back you guys were discussing piston choice so my question is was there a settle ment on which would be better 1(mil the chamber and don't zero deck) 2zerodeck and mill the pistons)
if it was mill the pistons would tlowe be able to do that when i ordered them?

You will find that often, to obtain your desired deck height, not only will the block need to be final decked by some amount, but most if not all of the pistons will need to be cut on one or either side as well to equalize them for zero or whatever you determine to be your objective. would this be the correct phrase in which you speak of wise one?

hey hank, i always see you mentioning methanol and i can tell you live by it how exactly does that work? i have a powerjection 3 that i will be running blow through and was curious how well that mixes with air how close to put it to the inlet of the T/B and how efficient are the tanks how long does... lets say a gallon tank last are you constantly filling it?

I am not good @ explaining things too well. There is good info out there how the methanol injection works.
I use Alkycontrol http://www.alkycontrol.com/
I used to use Aquamist 1S system, but it does not deliver much volume or pressure w/there pump. They too have switch to better higher pressure/volume pumps made here in the US.
My nozzle is mounted just before the T/B.
I use the factory windshield wiper fluid sized tank, holds approx 2.5 qts. With that size tank, I can run aprrox 6-8 1/4 mile passes. Just a guesstimate though, I never really tried to see how long it lasted. It all depends how much alky you are pumping into your engine, if you crank up the gain knob it will go fast but would be a waste. You can get knock if you are injecting too much methanol.
I use 100% methanol & would highly recommend it to most anyone running a turbo or supercharger.
My Syclone engine is completely 100% stock untouched long block. Cast pistons & all. On pump crap 91 octane fuel, I can run 26 psi of boost pressure & have dyno tuned my Syclone w/methanol injection. Peak torque was 604 ft lbs, because of the torque multiplication from the torque converter then settled down to 450 ft lbs from 3300 - 4800 RPM 396 hp peak & averaged 375 HP over a wider range. These readings are taken @ the wheels w/a dynopak dyno.
I would say if you drive day to day w/a turbo & methanol injection, I would think a galllon would last a week, it all depends on a few things, if you are doing high speed long runs, it would not last that long, but if you drive halfway normal a gallon should last a while. It is much much cheaper than filling up w/race gas all the time, who can afford that, not me for sure.
Methanol injection allows you to run @ race gas power levels @ a much lower cost.

Hey hank
What/how extensive is the machine work for installing screw in studs and at what point are they needed?
