We have a nice trophy of a piston with a valve head firmly planted sideways into the face. Expensive trophy though.

yes typo 560, the cam is a 222/224/112, i wont be using them in a motor again, my 918's wont be going back in my motor, we have been using some other springs and the makers tell us they are good for 610 with agressive ramp rates,

hahah muz, thats oil and coolent LOL
