I have an 98 T/A A4 LS1 with a spun bearing but the silver lining is now I have to rebuild and I think I’m narrowing down what I want to do but really it's still in theory on paper so I was looking for some constructive criticism, here goes nothing

Starting at the front: Cold air intake, 92 mm ported throttle body, 85mm mass air flow, LS6 intake manifold. Inside: crank shaft bearings (that’s what’s f*ked up) LS2 timing chain, ported oil pump, (I’ll have to wait and see what the crankshaft, connecting rods and pistons look like) a 228/228 cam, push rods, new OEM springs and rockers, LS6 CNC ported cylinder heads with LS6 valve stems, larger stall converter, and all gaskets bolts… I already have a 3" true duals from TSP.

My questions are will this stuff work together or not? And I’m still trying to figure a ballpark rwhp number and my compression ratio before I start turning and burning. Any input helps, thanks guys... and I'm sure there's some F-body girls too!

better valve springs and ls6 wont accept a 92mm tb for starters

If you're gonna run an ls6 intake, don't waste your money on a 92mm TB. Port the stock one. The throat of the intake isn't any bigger than the rear of the stock TB, so the big one will gain you nothing.

Ok Ill just port my stock one, but my concern is the cylinder heads with the cam is that a good match up or am I waisting my time and money.

Change your springs or you will blow your new engine...hardened pushrods? I hope..
Have a look at assembled SB too, its cheaper and safer sometimes than having yours rebuild locally by incompetent plp..

Is there a difference between the beehive shape and the double spring or does it only matter depending on the set up?

IMO jut get Patriot duals and be done with it...

With that size cam beehives would be just fine.

If you use OEM valve springs on that cam you'll blow it up again. Also go with a chromoly pushrod. Use better then stock rod bolts too. I think stock LS1 rockers are pretty good too, might not need to replace them maybe do the trunion kit on em.
