Somebody on Class Racer used to sell header plugs that had the moisture absorbing crystals inside, maybe someone on here remembers who was selling them.

Dan Dvorak was the racer who made them.

Thank you one and all for sharing your knowledge. This bunch of racers has more experiential knowledge of what works and what doesn't than any body else could imagine. I got the heads down to bare castings,the intakes all look great, all but two of the exhaust seats need help. I plan to reface them , lightly touch the valves, new seals, and new springs. Now, with a 327,250 horse, 1.72 intakes,1.500 exhausts, Elgin rockers, not rollers yet, new Comp springs,what spring tension should I go for?I was thinking 350 over the nose, 180 on the seat. This engine is done by 7000,so i wasn't going for broke on the spring pressures.If it was a 275 horse with roller rockers, that would be different. This engine does have a steel Bullet cam and Smith lifters. Wouldn't it be great if we could run a rev kit on a stocker motor? Just thinking.

I run 160 on the seat with comp springs, done a back to back test at the track and boosted them up to .050 before coil bind, which I believe was around 200 on the seat. It ran about the same. I put them back to 160. This was on a 295 hp 350.

I bought 3 cases 6 years ago and only have one can left.

Orielly's sell Marvel Mystery Oil

Nerf balls make great header plugs. They make lot of different sizes of little footballs and other balls. Cheap and easy to find at WalMart, etc. Also wont hurt much if you crank it over and forget to pull them out... they just shoot out of the headers. Might have to chase them down.
Let the pipes cool before sticking the balls into the pipes.

Good luck.

Fogging the motor when not in use as well as plugging the collectors works great--- we also replace the spark plugs with dessicant plugs at the end of each day to control moisture in the cylinders-- FED 387
