RAIST-
Are you doing this install on a stock block with stock heads? You may run in to piston to valve clearance issues. TSP recommends that you check clearance with that cam since it is so close....Not to mention stock heads/intake wont flow where that cam is designed to make power.
You should buy a pushrod length checker before just installing whatever pushrods you have. The MS4 has high lift, fast ramping cam lobes that are going to beat your valvetrain to ****, especially if you plan to reuse your stock ls1 lifters. (You would have to remove the heads to change them)
I hope the PRC springs you have are the high lift rating...MS4 is advertised at 0.649 lift on the intake, and base PRC spring kit is rated to 0.650 lift. Also, you would need retainers for the dual springs if you didnt buy the PRC kit; stock retainers wont fit.
With that said,
Thunderracing sells a machined tool....at $105
...sometimes you can find these on ebay for $40
Or, you can go to Home Depot and buy 5/16" wooden dowel rods.
There are a bunch of people on ls1tech that sell custom pulley installers; basically a threaded rod design.
Assuming you have all the tools necessary, torque wrench, good spring compressor for the duals, etc....
You need:
Timing Cover Gasket
2 water pump gaskets
front crank seal
spark plugs
Crank Pulley Bolt
Assembly lube, coolant, high temp rtv, oil, oil filter, loctite
You should consider replacing the oil pump and oring, and upgrade the timing chain while the front cover is off.
