One question, you stated "- Lunati Roller Cam .678/.678 lift, 278/286 duration @.050, 112 Lob Sep, 108 Centerline (~.030 more lift, 6 degrees more duration on both int & exh, same Lobe Sep and Centerline)".
Is this spec'd with 1.5 or with 1.6 rockers? If its .678" lift with a 1.5 rocker and you are using a 1.6, I think the spring will be very close to binding at lift. Documentation on those springs (PAC 1325) say bind at 1.150" which would make it real close, too close I would think. Just something to check.

The build looks cool to me I would put my money on at least .2 sec. quicker.
