Dont forget to to use headbolts with washers. These also use spark plugs with washers and use some antiseeze on the plugs as well. I'm sure you already know that, but you would be surprised on how many people dont and mess the heads up.

Almost forgot you have to use self aligning rockers or aftermarket guides. If you use the stock guides with the factory self aligning rockers the guides are marked for a certain position. some of them will have a number stamped in the corner and they only go on certain cyls.

I have some thrown somewhere and can take a pic if you need

i was just thinking for cosmedic reasons, but i wasnt thinking about the headers covering it. i have new ARP headbolts with washers, and i have some anti-sieze i can use(didnt think about that, never used aluminum heads before) i do have self aligning rockers that came with the heads. they were never used cause the guy i bought these from had roller tipped ones. thanks for all of the input guys. hopefully i can tackle this this next weekend. all i need is valve cover bolts for the new style valve covers and exhaust gaskets (i forgot to order them with the rest of the gaskets)
thanks again
