ok guys, here is the story so far. scan for codes P0301 cyl 1 missfire. recalibration cyl 1. check fuel and spark ok cylinder one - good. perform compression test cylinder one - has compression 210-215PSI. remove intake and perform pinpoint test for code P1411 - MDS solenois is faulty. remove cylinder head cover - intake rocker arm is broken/cracked. remove cyclinder head and inspect components. lifters are jammed, intake valve and pushrods are ok. the intake rocker arm is cracked on cylinder one. install new lifter, MDS solenoid and install cylinder head. fill with coolant bleed system and perform oil change after repair. start vehicle and road test - noise from the right side of engine after 10 mins of driving. isolate noise to the right side of engine cylinder #2, scan codes - no codes. remove right side cylinder head and inspect components lifters are jammed on #2 cylinder. remove all lifters, MDS solenoids and oil control vlave, clean out oil passages. Metal debris came out of the block. replace lifters and MDS solenoid. reinstall cylinder head. fill cooling system and perform oil change. Road test ok.
Now, my question is: will this cause me problems further on?????

maybe I should just get a new truck?????
