Need a Parts List For Top End Change - 1987 TBI 454

[Evil Trailblazer SS]

This is for my Mark IV 1987 TBI 454 Block (.030 over re-man short block) which I am ready to ditch the peanut heads and opt in some more power and torque. Here is my parts list.

Edelbrock 60499 Heads (Fully Assembled)
Edelbrock 3764 Intake Manifold
Edelbrock 8019 Throttle Cable Bracket
Edelbrock 7363 Gasket Kit (Heads, Intake, Exhaust, Valve Cover)
ARP 135-3610 Head Bolt Kit (For Edelbrock Performer Heads)
ARP 135-2001 Intake Manifold Bolt Kit
GM Performance 12495488 Cast Aluminum Valve Covers
GM Performance 14085759 Valve Cover Gaskets (Qty. 2)

I still need to figure out the following (Any help with be appreciated):

Timing Chain Set (plus gaskets)
Water Pump

I want to convert to a full hydraulic cam so the following may be wrong…plus I am not quite sure what is all needed for said conversion.

Lunati 60210LK Cam & Lifter Kit (New Part Number 20110710LK)
Pushrods???????? (Length TBD due to confirmation once heads are installed)
Rockers?????????

What else am I missing?
