Did you try to prime the oil system? -=Modified=-'s engine was noisy as hell when he first fired it up after the first install.
Remove the ignition relay (under the hood), crank the engine till oil pressure builds. After we repalced the O ring, it built oil pressure almost INSTANTLY...

I am going to pick up a new belt tomorrow and was hoping once it warmed up that maybe the lifters would fill or what ever. stock heads with 7.4 PR's recommended by thunder racing.
If I didn't touch the oil pump and never had noise before, is it safe to assume it's not the oring?

I went though 3 different sizes tsp recommended then got tired of thier guessing game. With out having the car infront of them that is all they can do, is guess.
If you are getting a sewing machine noise and decent oil pressure there is no need to worry about the oring. If you are getting a loud knock then I would go ahead and try the new oring and maybe new lifters.

^ huh??
ok.. Lemme see if I can get this. You installed a tr224 w/ 7.425 pr's. Buried at start? It pegs to 80+? Mod's car did that too, but it went back down to 60. It only did it once. Is that right? A little more sewing machine noise is normal. Once it starts getting loud, that BS flag should shot up, and you should be concerned.
What size head gasket?

OK now ya'll lost me. I thought somebody said that because the MS4 used LSK lobes on intake I believe and XERs on exaust that you would need two different length pushrods for a correct setup. And would the 7.375 work better in this instance than the 7.350s? I mean somebody said to add .075 dfor preload and he added .050? I'm not trying to shoot holes in the post just trying to understand it better because I just put together a MS4+LS6 PRCs cut down to .59cc chambers and I'm running the .040 cometics. I reused the pushrods from TSP that came with my TV2 I use to run and I don't even remember what length they were.

Thanks for the help guys, I started mine up the next morning expecting to hear that nasty sound again. To my surprise it was all gone and I've got a sewing machine with good oil press. I am bone stock gasket and head wise and 7.4 is what thunder racing recommended and it seems to sound fine on my 243/249 .613/.618 110 lsa.

Well I really really really don't feel like pulling heads again. Reason I would pull the heads is to replace the lifters that I just put in!!! Why? Because I didn't soak them in oil...just straight out of the box..into the block.
Thinking about just replacing the O ring and getting right length pushrods, what do you guys think what is the chance of my lifters being dead?

You will definitely need the right sized pushrods. THe oring makes a huge difference. My oil pressure shot up from 57psi to 70psi at idle.
