I would actaully use a .015" head gasket that I believe FelPro makes, which would put you at a perfect .039" quench.

As far as the cam goes, running a hyd flat tappet is a bad idea IMO. If you have to use a cheap cam I'd step to a mech. flat tappet not only for the increased lift (which those ehads need) but also for the high RPM stability. YOu say you won't go over 6,000 but that compression is more suited to a max RPM of about 6500, which in most cases is still safe.

LSA was already brought up so I will say that a 383 usually likes a tighter LSA than a 350 due to the added stroke. As such I would even stay away from the 110 and steer more towards a 108-105 for the street. Also, your mismatched intake will bennefit from a tighter LSA.

This is a link to a hyd. cam that will give you peak power at about 6500 RPM

And here is a link to an almost ideal mech. cam- http://store.summitracing.com/partde...4&autoview=sku

This one is really nice, but I would use EDM lifters with it as cheap insurance, its a little agressive, also I'd install it about 4 advanced

If you use any of those I hope you have a solid car and enough common sense to not do insane speeds on the freeway because they will pull hard.
