Silly question

I used ARP headbolts, and am having real good luck with FelPro .039 gaskets (1008s? IIRC), at 180psi cranking pressure. My first gaskets were .028, but I found them migrating into the valley at the first scheduled freshening.

>The heads were holding a lot of oil, so I dug some drainage channels on the back-ends, and now they are side-specific. They now have over 100,000 miles on them and have not given me any trouble.
>Not using the supplied valve-springs.Hughes recommended their springs (1110 IIRC) for their HE 3037AL cam with 1.6 arms.

>I drilled out the oil passage in the block and modified things to send a bit more oil up into the heads for lubing the shafts and cooling the springs. Don't know if it needed it, but I run the engine at 207*F so I thought it could be a good idea
