Well since I seem to be pushing coolant a little bit, I ordered up a set of L19's. They should be here Monday. I'm not installing them right away, but just want to have them on hand for when the next time the head comes off, I can just slap them right in.
Also, after a lot of thought and IM conversations, I purchased a new ETS FMIC

I got their Race core which is supposed to be good up to 980 CFM, which is about 100 more then I'm currently pushing.
Also been doing a lot of research regarding ignition amplifiers. At this point, I have no clue which one to get.
