For within a hundred bucks you will be able to buy the assembled CNC’ed Trick Flow small block heads.
Wouldnt even remotely consider the promaxx heads when the the Trick Flows become available
Key words in your post.
“When they become available.”
There not out yet and since there not, there not up for discussion or consideration if your ready to purchase & use now. It’s like your pointing at a ghost.
Every once in a while, some knot head says something stupid to me.
“You should have went with the Edelbrock Victor head.”
I say “That would have been an excellent choice IF the head was available at the time I built the engine but since it was not available, how does your comment help?”
