I really need some advice as im on a budget so on the civic it currently has a d16y8 has a warped head thankfully with only teh water pasage ways ive tried the blue devil head gasket sealer but ive inly used the small ones would it even be worth it to buy the big one as my brother has a d16y7 at a hpuse but its needs heads replaced the y8 has had some bad overheating times as one of the spark plugs gets harder as you loosen it i need to know if i should do the hesds on the sife and motor swap it or just spend the 75$ on the gasket sealer but im sure i should replace my water pump after that correct 

But if really like some advice on my situation cause if i have to swap it ima work on it and just try to do it in a night but thank you for taking the time
