Total "bill of material" for Aluminum head swap / Advice on where to save $ welcome...

You should be able to do the rockers for about half of the cost of HS ones. Speedmaster and PRW stainless rockers come from the same place and I think the SM are cheaper. About $250 not on sale for the SM. Even if you have to get a correction kit from B3 it would still be about $450 or less. Mike might have package deals ready to go for the TF heads. SM head studs or bolt kits are decent and a lot cheaper. If you are using pushrod oiling rockers, the Promaxx Shocker heads would probably give you close to the same power are a few hundred less than the TF. Your numbers are high on a few things but overall not that far off. The changes mentioned would save you almost $1000. If you want to use the top of the line names, you can't complain about the cost. It's a tough call sometimes.
