If you can, use a shopvac to vacuum out the coolant from the heads and block, makes cleanup a lot easier. Make sure you get ALL the coolant out of the bolt holes.

on top of this remove the water pump before the heads and with shopvac remove as much water thru waterpump holes on block, this will minimize water going into pistons/bolt holes when you remove the heads. less to cleanup there.

with wire cutters cut off just enough of the pointy inserts under winshield cowling or you will scrape your hand ugly.

you do not need to remove/disconnect a/c radiator, when ready to remove/install cam have a buddy hold it up away enough to clear cam ..

Be careful when removing the intake manifold. The brake booster vacuum line wraps around the oil pressure sending unit. Lots of people pull to hard and crack the top off the sending unit. It's cheap at the dealer if you break it, but try not to!

Use the shop vac to vacuum out the coolant from the front of the engine while the heads are still attached. When you finally pull the heads, youll have less coolant in there to spill.

After the heads are off, use a drinking straw and the shop vac to suck up any coolant that went down the bolt holes. Much easier than the twisted paper towel method.

+1 on the drinking straw and shop vac. Tape that thing to into the shop vac and use it to clean (suck) the coolant out of the holes. You'll be amazed how much you get out this way...

Wow! I like this idea. I wish I had thought of it before I did my heads/cam swap. Oh well, always next time!

I've used the q-tips with the long wooden sticks to clean the bolt holes. I don't know about you guys but my tranny dipstick was attached to my heads and I pulled off my heads and out came the tranny fluid. Now I need to service the tranny. I don't remember anything saying about unbolting the dipstick from the heads from that write up. Oh well

Another thing I did is leave all the head bolts in(just a few threads) when you first lift the head, reduces the amount of coolant that gets in the bolt holes in the first place.

Took 1-2 Hours to clean the bolt holes out with shop towels and brake cleaner

Sprayed the crap out of each hole, rolled up a towel into a cylinder, and pushed it into the hole until it hit bottem ... then twist it a few times to clean the threads.

Repeat 5-6 times until no more gunk/crap/stains were appearing on the towels

That method is now obsolete lol. Shop vac ???! All you need to do after you're done sucking them dry is go through with a shop towel and double check things.

Use a shop vac on the water pump to pull all the coolant out of the heads & block.
Swap is prety straight forward.

Oh yeah, take the grounds off the back of the heads before you unbolt the heads.

be careful with the torque wrench! some items are inch/lbs and no ft/lbs.

and just buy arp head bolts.. SO much easier than that torque to yeild crap.
