you using stock tubes or spring loaded?

If using spring loaded I would try these scat ones with the internal springs-
I ran these for 2 years without any problems. I think you can buy them by the set or individually.

But the best option of course is pulling the heads and using new stock tubes- Just make sure the seals are in good and the end of the tubes are seated correctly before tightening down the heads.

If using stock pushrod tubes, they must be stretched at each end and make sure when you put them in that the welded seam is facing upward toward the cylinders. You also can use a light coat of aviation sealant on the seals.

I have never had any issues with stock tubes. The mating surfaces have to be 100% clean. Once they look clean use a bit of laquer thinner or denatured alcohol and wipe the down. Stretch the tubes a bit, not much, and ensure the seams are up. A VERY light coat of oil on the seals if you are going to use anything. I put them in dry. I keep two of the spring loaded tubes in my onborad spares box so I wont have to pull a head in the middle of nowhere. The biggest thing that helps is keeping the mating surfaces clean. If you continue to have issues you may want to pull tins and check head torque.

I always had problems with stock tubes for whatever reason. These are easy to install and damn near bullet-proof.
