aluminum heads

You'll spend 600-1000 getting a pair of edelbrocks up to the level of the RHS head. Especially if you are comparing to the ones Brian does. The 875/pr heads don't have the really good parts in them nor the detail of assembly, finish cc etc.

Best bang for the buck head right now is the RHS head. No offset rockers, no special parts required.

Pick your parts, pay your money.

Same ****, different day around here when it comes to cylinder heads.
