I have a quick question. I went to install the water transfer tub onto the back of the heads. Well there is a little ring with a rubber seal on it that goes in between the bolt and the big metal junk that goes up against the head. Is there also supposed to be some kind of seal that goes on the other side of the chunk that goes against the head? I would appreciate any information asap, we're hoping to drop the engine in tommorrow. Also does anyone know the size of the bolt that holds the motor mounts to the engine, and also an opti-spark bolt size.

I can answer 2 of those questions.

There is 2 crush washer per banjo bolt. One under the bolt head and one on the cylinder head.

The opti bolt size is 1/4"-20 X 2-3/4".

Motor mount bolts are 3/8-16 x ¾. The forward one on the RH side is a stud for the negative battery cable.

Make sure you use antiseize cause those things are a pain to get out if they're stuck.

Those bolts arent normal bolts. They have coolant passages in them. Im not sure if you need one, but if you just use a standard bolt it wont flow coolant between the heads. There is a hole that goes from the inside of the bolts and comes out where the bolt meets the tube shroud part.
