Do not use block sealer!!!!!!!!!!!!!!!!!!!!!!! Temp fixes only make problems worse. Second a little water in the cylnders from the spark plugs is not bad, it might clean the pistons and valves a little. Too much water will dround the plugs. If you have smoke coming out the exhaust check you oil is ther water in it? Check you coolant is there oil in it. If you answer yeas to either of these the you got a blown head gasket. Get a GReddy metal head gasket and ARP head bolts or better yet head studs.

arp studs are much better better than bolts .
if and when i do another head i'm using a stud kit

theres not water in the oil...but i did notice little black dots in the coolent. bhg...dammit...is this something i can do myself? what does a bhg usually cost to fix?

Here in Mojave Desert of Calif. a BHG job cost about $1600 at a shop. I just did mine myself for $400 in parts and $425 for valve job, with a slight milling.
If you've never done a headgasket on an engine, you'd better have a friend with experience help you. And don't drink too much beer !! :lol:

you can do it dude !

it just takes some basic metric tools and a torque wrench

last time i pulled my head off it took less than 6 hours by myself . practice makes perfect i'm sure i could do it quicker on a N/A
it's just a lot of nuts and bolts that need to be removed it's not rocket science
i found this link very handy for my first one
