I just put the engine back together after new pistons rods heads by Lloyd comp 230-236 and 30# svo injectors and new opti. Then engine runs buth when we shoot the headers with a heat sensing gun # 1 & # 8 cylinders are approx 150-200 degrees lower than the other cylinders. Have tried switching injectors between cyl. have replaced plugs using TR55s have checked injector firing with noid. Data logging shows no codes. Thinking intake manifold leak but sprayed it with carb cleaner on outside with no change. Inside leak you would think would show oil smoke in exhaust but none. Unburned fuel by high hydo carbon is shown on sniffer in exhaust and burning eyes. Also re-adjusted roller rockers and did compression check 210# across the board Checked vacum good reading for that cam great on decel. ANY HELP WOULD BE GREATLY APPRECIATED.
