as u all know i pulled my engine due to head gasket issue back in may, i replaced the hg's & had some headwork done like had the heads checked, milled, valve job, 92lb springs & some port work done. i got it fired up over the weekend but it cranks up missing. im sure my firing order from coil pack to plugs are correct but does anyone have a diagram they can post just to make sure im right?? & also as long as the cam sensor or crank sensor wasnt messed with that stuff should be ok right? not need resetting or repositioning or anything correct? i think i have all the air out of the fuel system, it reads 40-42psi as it is turning over. however the pass side plugs are kinda dark while the driver side plugs are stil white, they were all new & gapped at 40 before cranking (R43TS delco) over the engine. i have checked the injectors 1 at a time while engine runs & they seem to all be firing. i turned over the engine with the crank sensor unplugged to try to prime the motor with oil before starting. the cam is stock with 118,000 miles, could it have possibly wiped a lobe? when it fired it had 60psi oil pressue cold almost instantly, although it did tick for a few mins then cleared up! Any help or advice will be greatly appreciated. Thanks

The #6 plug was smoked causing the miss, swapped it out & it runs good now..
