Aftermarket cylinder heads?? Which is best for the money??

first thanks to PHR and other great posts
OP you have several head builders including IMM here in so cal-- what I used to do

I'd ask about getting a bare head and have it loaded with known quality parts
or
No mater which loaded head you get I'd od hone all the valve stems for straight and then retouch the valve job for concentrict and to make it the way a pro likes it
non concentric valve/ seats break the heads off valves cut forsprings and seals if necessary
now compare your costs/benefits
I'd get with B3 on the rockers- which work best on which heads as
all the arm lengths are different
and some just work better (some have the rocker up on a pedistal for example, or Crane's quick lift BS
Plan on a mid lift set up as quality cam grinders use it to get the valve action they want
(worst thing yo can do is combine quick lift/ quick close with fast intake close like the comp 368)
calculate your compressions with the available gaskets
inspect your heads for surface finish in case you need Cometic gaskets
Be realistic and pick a rpm range before you get in deep so you can pick a cam duration to match which wll give you lift to soot for which will tell you what lift to look at for your head
