Thank you Mark. Easy to miss updates - we all are so busy. It was a happy house. Toby and Molly are both laid out flat in front of the fireplace.

Wow, crazy how fast a year+ can go. About another month and I will be in a position to be able to order the heads I decided on for this now slightly over budget build. OK, maybe a bit more than "slightly". It's been a painful and crazy 7 months. Our new puppy is now 8 months old and get's fixed next Tuesday. He is such an awesome addition to our family. Our older dog Molly has put him in his place when required and is enjoying the companionship.

These are the same heads I got, although I believe I have the 220cc.. I’ll have to check. Absolutely love them.

I'm assuming you purchased them loaded, with all the goodies like the stainless valves, Ti retainers, dual PAC springs, etc..?

I haven't ordered them just yet, but yes they will be fully loaded.
