Thinking about putting some hoses from teh rear water outlets on my super vic intake to the front crossover. First of all what size of line is best. Was thinking like a -6 line but maybe -4 will do it. Also on the super vic intake there are already tapped holes in the back but if i run them to the front crossover i will have to drill and tap new holes for my water temp unit. Anybody tried anything different here, What about one of those water outlet spacers that fit between the intake and outlet and have 2 holes in them made for this. Do they work alright or are they prone to leak?

The reason to run the lines is to help remove air and quench hot spots. The Spacer you are talking about also relocates the rad cap to a higher spot to catch the air in the system. We have used them for many years and only had two problems and both of those were due to the intake not being flat and smooth.
If you are worried about leaks get 2 of the gaskets with the adhesive on them and stick them together, this stopped the problems we had.
For the price difference I would use the
-6. Speedway sells a kit with everything you need.

Get the one with the cap or you may cause a high spot any it will hold air threr.

thats what i was taling about.. just a spacer between the elbow and the intake. Do the water lines get in the way of teh carb linkage.. looks like they are all trying to run through the same spot on teh left side.

If your water neck ends up above your radiator you need the one with the cap.

If you get the good ones with the cap they have an overflow tube or you can drill and tap it for one. We just always ran a 25lb cap on the spacer. The idea with the cap is it is a high spot to get the air out. We have tapped them and put a small valve there to bleed air out after it was run, you can connect a tube and direct it away from you.
If you get air caught in it it could heat up and Blow the hose off or split the radiator, that would be worse than loosing some water past the cap.
We have drag raced or ran oval track for over 17 years and never had a problem with running the one with the cap, We ran a 221inch wb rail at 8:60's in the Quarter mile with a small block and a 12 X 16 inch radiator and never had the problem of blow by.

Peterson Fluid Systems has a nice riser to use to plumb in the back of your intake. http://www.petersonfluidsys.com/coolsys.html

Lefthander has it in their catalog too.
