Default Fast intake and coolant crossover

Just bought a 78 mm fast for a good price to replace my ls6 intake. Kinda funny guy bought it and never used it had it for 8 years and its brand new in the box so I said why not. But either way is there any other way then buying new coolant lines? Could I modify the stock lines? Also I would really like to have all 4 corners vented but just want to order what I need by tommorow. Anybody have some suggestions?

What I'm doing is getting 2 ls6 style front cross over's and running a line from behind the intake around the side and connecting it to the front before it goes to the radiator.

Op,
Just a tip for the valley plate cover and fast intake.
I took a countersink to the plate and tapped the m8 threads in block for 5\16-24.
I got the countersink allen bolts for about .20¢ each.
Not all the bolts need it. Just the ones interfering with intake body.
I spent less than 5$. And didnt pay for the fast button heads.
Done it for few other folks who bought intakes without bolts.
Can also use 5/16-24 button heads, if not countersunk bolts
Thr m8x1.25 pitch is very close to the 5/16-24.

If you want to do it on the cheap get another front crossover and reverse it on the rear heads then run a line up to the front T into the front line plumb it to your water pump or radiator

Rig the 2 crossovers and use the cash saved for something else. I reccomend the truck crossover in the rear because the outlet tube points up instead of laying flat like ls6. Use ls6 in front of engine. Tie it all in with 3$ brass T or Y. And 3-4$ worth of tubing and hose clamps
Mine been on for 6yr and been on different engines
In my car.
