Does the coolant and/or oil need to be drained in order to do the replacement properly?

Any input would be helpful.

i didn't drain the coolant when i did mine, but i would if i did it again. it makes a mess. no need to drain the oil though. it's a cakewalk though, good luck.

i would with the antifreeze, the oil wouldn't be bothered. Just besure to have A LOT of towels, don;t get water into your cylinders, and square off your head to see if you have any warpage. i would get some ARP head studs too....but it all depends on you and your budget. good luck bro
