Head for boost.
Since I have to get new heads, what is a good factory style for head for boost. nothing over $1500.00. I have patriot gold springs and stainless valves that can be swaped.
I have heard alot about deck thickness, lifting and sealing. I have studs and will continue to use MLS gaskets of some sort. 18 to 20 lb boost at most. will stay around 14 most of the time. 6.0 iron block .030 over. I want to get this thing going again, but for good.
thanks.

For the higher boost levels you're better off with a thick deck such as what the AFR heads offer, although they're more money than what you want to spend. Bob

I've never seen the as cast TFS heads but I know they can be bought and are around that price range. Later you could take them off and send them in for the cnc program to be run on them. Not sure if AFR has an assembled as-cast offering but they would likely be just as good. GM also just released the as cast LS7 6 bolt head that may come close which I believe has a thicker deck. That would require a different intake.

I'm buying some TFS 220cc as cast heads for my project this spring. You should look into them and take the plunge. They supposedly only make 10rwhp less than the CnC'd version and have a nice thick deck. Speaking with TEA they suggest doing some minor bowl work (under $100 worth of labor) and they are good to go.
I'm doing a 364ci forged iron block with doweled main caps (keeps them from walking around) and a GT88 T6 turbo. I want to make as much power without having head sealing issues. Hopefully that is around 1000rwhp. Going into another 3rd gen RX-7 I have. 2850lbs is the goal and some silly mph/ets for a street car. T56 transmission is the plan.
