I have a suspect blown head gasket so i am looking to the repair side of things, which is circa 3-5k
my symptoms at the moment are only very minor, after an extended period of hard driving my coolant begins to be pumped out of my reservoir into the overflow (already replaced caps)
levels are normal cruising.
my question is, if the engine has never overheated is it still necessary to deck the block before replacing the head? is it a compulsory thing or is it just insurance?
reason being that i feel i'm capable of removing the engine and changing the head gaskets, putting in some arp2000 and be done with it, but will it last without a deck job?.
