Ism going to look and see if I can see with them on the truck. Can I just swap heads for something without the notch? As for getting them worked this area isn't so great for getting any LS work done.

Edit: couldn't see crap. I'm stupid for thinking I could. However, they are 706 heads.

 

This???
Chevrolet Performance LSx Timing Cover/Damper Seal 12585673 - Brian Tooley Racing

I know I need a timing cover gasket.

 

I would do both since your already down there. Once you disturb the seal they always seem to leak shortly after. Especially with over 100k on the clock.

With the 706 you might get luck and not have to worry about the notch. I have seen them on the 862 truck heads and the 853/241 LS1 heads. I don't recall ever seeing them on the 706 heads as of yet.

There was an old document online which is now long gone. If I recall correctly it said the 862 truck heads could have the notch from 99-01 any you needed to use the correct gasket. I believe since the 706 were cast at a different foundry with a different process the notch was eliminated. How ever in the past they have been known to crack around the bolt holes and loose coolant.

 

That is the castech issue correct?

 

Thats correct. If they haven't cracked by now chances are slim there going to.

My 00 has them and they haven't cracked with over 160K miles on it.

 

So this is what I have...
214/220 cam
Brian tooley dual springs
Comp magnum 7.4 rods
LS7 lifters
Water pump gaskets
Crank bolt

What I need to buy....
Head bolts SDPC 22.95x2
Head gaskets SDPC 29.80 for MLS gaskets
Timing cover gasket BTR 15.99
Lifter trays BTR 7.95x4
Header gaskets BTR 9.99
LS2 timing chain summitracing 29.97
Headerbolts only need one can't find anywhere
Intake manifold gaskets still looking
Blue oring for oil pickup tube BTR 4.99
Crank seal BTR 15.99

Any help or cheaper sources would be greatly appreciated. Also anything I'm missing.
