Another main thing is the thread depth, the thread on the stock bolts is 2x longer then the thread on the new studs. How would I go about installing these, I've researched a little but can't find any info on a situation like this

 

num5golden you are correct 203-4204 i was thinking off the top of my head and about the thread length you should be fine i put locktite on all of the bolts and just changed the head gasket again due to exhaust oil smoke due to oil control rings at 6300 rpm launches and the head bolts held up fine just make sure you break them in before drag racing your lancer

 

Just installed last night, good tight fit, all seems to have worked, i still have manifolds to strap back on it,+turbo, piping, fuel system before i can let everyone know for sure how they hold up.
Should I think of re-torquing after a couple hundred miles, I know there isn't an exact final torque considering it's (torque, 90,90), I tried checking with my torque wrench afterwards and got to about 116Nm before I felt they would start tightening more. Kinda a "who knows" question I know.

 

From my research evos take 65 lbs i put 70 on all mine to make sure but not too much to flatten the gasket and also do tighten after 400 easy miles or 50 miles hard driving from experience i forgot to do it once and 4 of the 10 was at 50 lbs just to put that out
