Outer Limits 4x4 Board

ok done the head in my mav and all i got left is to do an oil change!
firstly should i run something through the engine to clean out any sludge that might have gottin in cause of the cracked head?
secondly what else might i need to do besides fill it up with coolent and water?

im prety sure theres something ive forgottin but im sure some one will remember!
cheers in advance!

I'd change oil & filter, give it run on the fresh oil & change oil & filter again. Dont put coolant in for the first 1000km after that flush the radiator & top it up with coolant & water.

ok no probs was going to do that! it seams fine only have to try and get more water into it as it only took 10 litres to fill as apposed to 15, i waited for the level to go down once the thermostat opened but still must be air in the system, ill get mechanic to sort it out while he does the rockers, i cant work them out and its prety tappy!
