how to complete bare heads
I can get dart iron eagle heads 215cc runners and 62cc combustion chamber for $200 for the pair. They are bare though so can someone educate me on what parts are needed to complete them and is it easy to do? Also around how much would it cost to finish them

New or used heads? Either way prob need a valve job. Then you'll need the correct size valves, springs to match your cam, retianers & locks, rocker arm studs, valve seals, shims and guideplates. You can go china cheap or quality parts $$$ Last set of used heads I bought I got $50 off for letting him keep all but the valves, it was the junk stuff most heads come with. Still by the time you add up all the stuff you need, you could prob buy a decent set of heads ready to bolt on, if you don't want the trouble.

I prefer to set my heads up with stuff I pick out, those heads I got with the valves I already bought $200 of valves.
Still $200 for new bare heads seems like a good deal. Are they platinums? You could prob put em together with better stuff for the same or a bit less than assembled.

and you can have someone assemble them and check guide clearance seat concentricity check the castings for a thousand other things, thats the way to go.

The only way to know what it will cost is to price out all the parts you need to complete them. Once you do that you can make an informed decision on whether you will be happier with buying a set that's already assembled or building exactly what you want.

Are you going with roller cam kit? Comp Camp K-Kit that includes the cam, lifters, springs, keepers, locks, seals, cam button, timing set, is about $950. Add guide plates for $50 and I/E valves and, assuming you have only to assemble you would have a BUDGET roller cam swap at about $1,250 with all-new heads and valve train. Toss in engine gasket price and you are still getting a bargain.

I will be using the lunati voodoo cam 262/268
My two options are this:
1) buy zz4 58cc heads with new machine job done with receipts and valves set properly with single springs and guide plates...etc the whole 9 yards for $400
2) buy dart 200cc runners and 64cc combustion chamber bare heads for $200 and use the rhs bare head assembly kit for $140 and put them together myself.
Which one will produce more power?
better value?

I spent $600 on the rebuild as all guides were also shot, cleaning, resurface, assembly with my new parts (reused the valves and guide plates only).
If rebuilt, you are getting a deal at $200. Hope that includes guides and valve seats.

Bare heads need to be gone through buy an expert and assembled by the same if you have a fair amount of coin in them. There are so many things that can be out it's not even funny, even from the good USA manufacturers. I did most of the work on my motor except I let my buddy set the heads up correctly, hands up for who's have a spring height micrometer.
You should run the gammet from cc'ing the combustion chamber to making sure the head is straight and not high on on corner and low on the other. Then they should be gasket matched to the intake you are using.
Seems like a no brainer but it's not when you get into stetting the correct closed spring height to to checking each and every valve guide, a tight valve guide at high rpms is about as bad as any other clearance not being set right, BOOM !
