    Default which way should i go

    picked up a set of twistys and they have the tubes for a one way valve (crankcase evacuation system) and i have new valve covers with no holes.
    should i set up the evac? or a puke tank ? both ways i have to weld in fittings and have lines made.

    personally, i would go with the evac tubes...u already have them & would save you $$$ on the puke tank!!!...just weld some -10AN fittings into the valve covers, either on the ends or the top & get some ss line & your good to go ...just my .02 cents

    Thet tubs are the least expensive way to go and are effective. The puk tank is cool, but requires more work and $$$ either way you're cutting holes in those pretty hew valve covers just depends on if you want to show off your superior fab skills.

    Yes, they will work with injected headers, but not with "wet" headers like lightnings, or others that put all the dump water into the exhaust. IMO

    The air valves have a ridge on the end for a clamp an hose, cut the ridge off. The fitting is actually a water heater gas line fitting, they are steel. I put a bead of high temp silicone around the end put it on and then a small tack weld to hold in place.
    I have this photo, not a real good one i can get a better if you would like to see it better.

    You don't NEED to weld anything.
    If you buy the Moroso pan evac system, they come with check valves (that will screw onto your tubes) and push in breathers.
    I used a hole saw to cut the valve covers and it worked great.
    If my new headers had the tubes, I would still be running it.
