Dyno #'s with Trickflow Heads

71 340 bored.30 over. Just a basic rebuild not a high performance build. No oiling mods & unfortunately never measured compression. Did do a compression check on each cylinder with new heads. Numbers were consistent cylinder to cylinder around 165psi give or take 5psi. Though that seemed a little low with the smaller cc chamber than what was on the EQs

It's all about the application.
Stockish 340...small'ish cid
Eq heads port sizing is a velocity winner.
Turn the CID up or raise the compression to 11.1 and lift the valve .575...and the TF heads will really come alive.

You basically put the cart in front of the horse.
