With my mods in my sig, any idea on why cylinder number 7 keeps breaking ringlands? This is the second time in 6 months. I had some forged pistons to throw in the last time, but money came up short so I sold them and put a stocker in. A forged set is definitely going in this time, but I just don't understand why number 7? Heads are 64cc as well, cam is 234/246 .602 lift.

That's a pretty open ended question. It could be anything from install error to a tune problem. I know #7 i normally the first one to go so there is no telling. There are people that push 500rwhp on stock parts so I don't know.

It will help if you vent the rear of the engines cylinder head for clearing water over the chamber. You can use the old factory water vapor manifold if it fits under your intake, or plumb it above the intake.

IIRC - I read here that #7 is last in line on the fuel rail, and members here have cleaned debris out of the rail that created a restriction to that cylinder. I don't want to steer you wrong, but it might be worth investigation.
