I really like that simple setup Conan posted. Good use of other GM parts

Not sure how this setup will work. Is your coolant fill point above the top of the cross over lines? If the fill point is below them, there will be air trapped in there. Sure the lines should have coolant pumping through them but at the same time the front and rear of the heads are pushing water out. So you have two things pushing against each other and not flowing. Maybe that is why GM decided to get rid of the rear steam ports? Hope that makes sense. I will draw up a picture to explain better.

Here is my wonderful picture. Again this is just a theory I have. In a perfect world, all the pressure will bleed out the front feed back to the radiator and all will be good. But this is my worst case thought.

Well I finally got around to running mine today. The lone brass tee will be swaped out for a nice stainless one tomorrow.

I took the same crossover tube as used on the front, w/steam tube, and used it on the rear.
The steam tube was cut (too close to firewall), somewhat, then flared, then capped. The crossover fits perfectly to the rear fittings...not as elaborate as the "all the way around" system, but works just fine.

Hey Guys,

I have a ls1 gonna run a 76mm turbo try to get 800 plus rwh. I have the coolant lines that run basically all four ports together. Is that best, or just the two fronts one line and the rear two one line. it came factory with the back blocked off. my question is whats the best configuration tie the fronts together and the back together. L-Brown where did you get the nice fitting like that.

It's best to use four corner cooling. It doesn't really matter how you get them all tied together into the one return to the radiator.

All the coolant flows from the head corners towards the radiator.
