Default 1.6s/918 install next week, looking for a few part numbers

OK so I have

918s
1.6 Pro Mags
7608-16 Magnum pushrods
614-16 10* locks
hardened guideplates
7/16 ARP studs

I am looking for the correct retainers, seats, and seals for my setup. I am pretty sure I will need the 795 retainers and 4705 seats, but just want to play it safe. Are titanium retainers worth the extra coin? As far as seals go should I go with Fel-Pros or GM? Thanks for the help, and let me know if I am missing anything.

retainers im using are the comp cams 787-16 which are for beehive springs

the locks are the comp cams 648-16, they are 7* 11/32 locks for beehive springs with the 787 retainers

seats are the 4705-16

not sure what the difference is on the 795 compaired to the 787 for retainers, both say they are for beehive springs.. just one uses a 7* lock and the other a 10*

EDIT:

according to summit, the 795 retainers are for the comp cams 26986-16 spring... and the 787 retainers are for the 918's.. which would also mean you need the 648 7* locks as well.

I am using 10* locks due to future cam choice, so I need a part number for the retainers for the 10* locks.

i searched summit and compcams but i dont see a retainer for beehive springs and 10* locks for 918 springs.. send a message to comp cams.. they are pretty fast at answering their messages.. or call them.

795s are correct.... or if you want to go for a lightweight retainer I'd get the tool steel units for a beehive spring, they're within 2 grams of the titanium stuff, 1795-16 is the tool steel p/n.
