Installing a new head, need 230 cu in torque values - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I'll be replacing the head on my truck in a couple of days with another I'm having re-done. Does anyone have the torque specs for a 230 head? Any "hot tips"? It's pretty straight forward but I'm sure someone has some old secret they want to share.

Very important:
Make sure water pump is installed to reinforce the block.
Front 2 near water pump only go 85 ft/lb, to not crack the water pump holes, the rest of the head bolts torque to 95.
Torque in sequence, in 4 stages, gradually working up to final spec.
Use thread sealant like ARP thread sealant.
Use lube under bolt shoulder and washers.

Sequence: Front->

14. 10. 6. 2. 3. 7. 11

13. 9. 5. 1. 4. 8. 12

Good luck.

So I've been reading up on the head gasket install and I'm understanding to use no (none, zero, zip, nada) gasket sealer what-so-ever, just what is mentioned above on the bolt threads.

I'm very mechanically inclined, I've just never changed a head gasket on a big engine before. I don't feel "challeneged" at all, just need to verify good info and technical info as well as welcome any tips from the folks that have alot of experience doing it.
