Highest flowing sbm heads?

Freakin A brother! Here here!
We are in the same boat. Just retired last year and I’m neck deep in LA parts I plan to have fun with.
I’m not in the biz of resale or out to try and make a mint on my used parts that are normally list inexpensive but then there are the guys that want it all including and extra $50 in there pocket for doing you the favor of taking interest in your parts!

Un freakin believable!!!!
Tell me about it , that is why I never sell my parts , i put 10g of parts in a build and the cheap asses want to pay 4g for a complete running engine **** that I'll use it as a boat anchor before i sell to some low balling a-hole . Parts cost big in commie Kanada
