Eww.. nasty hard dirt inside the engine. Try to blow all that crap out without getting it down in the pan if you can. Once you have that clean pour a few gallons of diesel through and drain it. .Trying to rinse out any garbage that might have made it into the pan.

No.. i think only vettes got roller rockers in any of their motors. Not sure bout LS stuff. Roller motor just means roller lifters.. the most important part.

ok so when i lift up my motor with a hoist i use an engine leveler that bolts to where the intake manifold bolts onto, should i wait until after the motor is in the car to install the manifold because i have to remove four of the bolts to put the leveler on? or should i just go ahead and put manifold on?

and should i find another place to mount my coil? considering everytime i need to adjust timing i have to unbolt the coil bracket which is bolted down with one of the intake manifold bolts

im just thinkin that its probably not a good idea to undo the bolts but who knows maybe the other 8 bolts are enough to keep it sealed while i get it in the car and adjust timing

You can undo the 4 bolts from the intake to install the motor no problem. Just make sure you torque the intake down properly with all 12 first. Then use longer bolts for the leveler. I like to have the intake on if I can because it helps keep debris from entering the motor. My HSR however, I put on after the motor is in simply because of how tall it is and it's installed as a unit with the injectors already on.

You can move your coil anywhere you want.

You can get some beveled washers from Tacoma Screw for ~$1.5/pc. I did that when I put my HSR on. You have newer heads and older manifold, correct? IIRC it's something like 15* bevel? It's off by a degree or two but I never had any issues in the few years I had my HSR on.

Or are you going the opposite direction? Old heads and newer manifold? I can never remember which had which.

as paul said.. just elongate the center intake holes on your TPI manifold. with proper gasket and some teflon sealant around the intake bolts, should be no issue.
