they are wiseco pistons designed by endyn. as far as i know they do not make a k series application as of yet. although i believe import builders has a similar line of pistons for Ks.the combustion chamber on a stock k series head is quite good, but you want to minimize the dome at all possible by milling,thinner gasket, etc. if your planning on sleeving and enlarging the bore this would be your best option of increasing compression and doin it safely as it will allow you to run a more flat top piston which is ideal. thermal coatings on the piston tops and chambers can also help reduce detonation
