yeah i was going to soak the head in oven cleaner then drop it in an ultrasonic as long as theres no rubber seals on the stem of the decomp, before lapping it in. curious to see if ill need to do any work on the squish band, or if the stock head will match up well enough. I did some reading in the tuners handbook, and a friend has a lathe and mill in his garage. We were both machinists for a brief time so i think we can get ourselves into some trouble.
If the piston matches up to the stock head well enough without any weird clearance issues i will just leave it as is to lower the C/R a hair and hopefully mitigate the heat issues.
