Simples1988comanche

1988 4L Comanche i changed the head gasket, replaced the head cylinder with a new shop one. My jeep doesn’t have a EGR Valve because i put aftermarket headers on it that were for a Cherokee smh. No 02 sensors in my exaughst or headers right now. After replacing my head gasket the jeep would start and run but the coolant pressure going into the reservoir was weaker than what it was before i replaced the head gasket. Now my jeep is misfiring kinda. I crank it and it tries to start but it dies and it dosnt let me give it gas & it kinda bogs down. idk what to do two videos i put below are after i put the nee head gasket on. All of a sudden the jeep started misfiring and bogging and struggling to stay on. IMG_5130.MOV IMG_5129.MOV

Was a dead battery lol new problem I'm running into is a weak coolant flow. I can see coolant flowing into the overflow tank but its a very slow stream compared to before i swapped the cylinder head. Could i have a bubble in my thermostat? Water pump has been replaced in the last year or two and has little run time.

I have a 1988 Jeep Comanche. Had a head gasket leak so i replaced the head gasket & also purchased a new cylinder head. Now my Comanche is hard to start. Battery was dead, we jumped it but it took a few tries of cranking to get it started. It would sputter but not start. After it started and it we shut it off we couldn’t get it started again. Just it sputtering like its trying to start. FullSizeRender.MOV Video won't work
