I noticed there are no valve pockets cut into your QSC pistons. I understand CIS pistons do not have the valve pockets because of the SC cam design. With your WEB Cam 20/21 you will have a .485"/.452" valve lift. The QSC piston domes do not look like the stock CIS piston tops. Maybe with the 20/21 duration of 258*/246* it will work out but it just caught my attention.
