493 Build

I am currently collecting parts to build a 493 stroker. Wondering what people's opinion is on the route I'm thinking of going.

Was planning a 440 build and was about to order parts but a freshly machined 493 block came up for sale so plans changed.

Currently I have 99% of parts for short block.

Freshly machined 493 block
Eagle forged 4.150 stroker crack
Eagle beam h conrods
Diamond pistons (domed)
917 deep sump
Custom headers (2" primary into 3.5" pipe work)
Msd billet dizzy, ss blast coil and 6al box

I am thinking of of going with a
trick flow top end kit (Trick Flow® PowerPort® Top-End Engine Kits for Big Block Mopar 440 TFS-K616-620-576)
Holley sniper X efi system


Things I am unsure on is

A. Is it worth installing a 440 source gridle
B. Weather to go for a mechanical or electrical high flow water pump
C. To use the trick flow high rise manifold (comes with top end kit) or use torker 2 manifold that I have.
