better design
I like the extra indents on the intake and exhaust sides of the piston to create a better vacuum for faster intake and exhaust movement through the cycle. I always use wiseco for all the top ends I've ever built and the new advancements in design are awesome. Also, I looked all over the internet to find the cheapest piston kit using the wiseco part number and dennis kirk STILL has the cheapest anywhere! Not even eBay could compete!
