I have a friend that ran the total seal claimer series gapless rings and he loved them. He had no blow by coming out of the breathers on the valve covers. I am running a 355 2 valve relief speed pros fully machined, with double humps, the engine was fresh at the begining of the year and has about 15-20 races on it. I am going to pull it down and re-ring it, i ran a set of plasma moly speed pro file fit rings. The engine ran good but i always had to wrap rags around the oil breathers to keep the oil from blowing on the headers. Also i have seen impressive horsepower numbers in magazines with the gapless rings compared to gapped rings, but i have read lots of bad stuff on here about them. I am on a budget so anytime i can make cheap power i am all for it.

If done right, you will have good results with either ring. I prefer gapless.

Use the Speed-Pro ring's, and gap them properly. .021"-.022" top ring gap, and .024" 2nd ring gap. If your block was not hone with torque plates, you will always have some blow-by, regardless of what ring you use.

Ran molly at .022 had same kind of problem freshened with gapless not so bad.Put in plan iron lots better, machinist didn't use torque plates so iron worked better because it broke in quick or formed to the scratches better
