You are looking for an easy way to improve the performance of your Stage6 R/T cylinder? All you need is the upgrade kit suitable for your cylinder!

If you have, for example, a cylinder that comes with 2.4mm inner cylinder head cap, you choose the upgrade kit for this cylinder. It includes an inner cylinder head cap that reaches 4/10 deeper into the cylinder; this will be balanced with the base gaskets included in the delivery, so that the recommended squish band of 0.40mm remains unchanged. This simple modification raises the complete cylinder, and therefore also port timing.

If the cylinder has ~192° exhaust and ~127° transfer port timing out of the box, these will be increased to ~194° and ~130°. The result is a clearly measurable performance plus.

Also included in the kit is the spark plug (NGK nickel-alloy B-E10.5) we have listed as replacement part in the cylinder manual. Rarely has a spark plug convinced us like this; but thanks to this one, we’ve now managed numerous times to get a performance plus of a half hp on the dyno with different engines – simply by replacing the spark plug!

The flange included in the delivery has been conically machined off.

All in all, this is an amazing package that will boost your engine’s performance for a very fair price.

Tech tip: Using our port timing calculator, you can also (against our recommendation) choose another combustion chamber depth for your cylinder, depending on whether you want to raise port timing just a bit or a lot.

On the cylinder kit, next to the specification of the piston version (A, B, C), you will find which inner cylinder head cap is included.
Scope of delivery:
Inner cylinder head cap, base gaskets, spark plug, flange.
