No, I am talking about inside. I want to send the block, heads, and upper and lower plenums to have then dipped, soaked, what ever it is that gets done. I can take care of the outside. Or is there something I can soak the block and plenums in the get the gunk out of the ports, crevices, and where ever else it hides?
