Today I just finished dropping in my engine every is torqed down and ready go...YEAH riiiight. Well here is my problem..First off let my inform you that this is a fully built h23. My head was built by KMS with a full titanium valve train upgrade. I upgraded from my si valves to vtec valves stock cams and rocker armms. I went to do my valve adjustment and Ive backed the adjusting screws all the way out and still cant get my feeler gauge to slide in and out. The book calls for 0.004-0.005 gauge on intake and 0.006-0.007 on exhaust. Ive backed out every screw and cant get a single gauge to slide through. I dont even think my valves are closing completely cause of such bad back fire. Anyone know what might need to happen or anything I can try?
