Talked to Texas Speed this morning and walked through some questions after receiving my assembly. Quite frankly, the main purpose was to ask about the pistons. I wanted flat top pistons, but they did not have the particular brand I originally ordered in stock. Recommended a different brand (next up in quality) for the same cost. I opened up the box, pulled out the paperwork and read the word "dome" in the balancing portion of the paperwork - however they did have the same net piston volume. Immediately went to the box and pulled out a piston. They are beautiful by the way (I will post pictures later) but they did not look like a "true" flat top. After talking to Derek, my concerns were put to rest. He also answered the numerous questions I had after reviewing the paperwork. Looking forward to putting this thing together - but will be taking my time.
