Trick Flow small block heads

In my mind it I thought it was [email protected]....... but the 255 would work too.

The fast rate stuff does work well...... when/if it makes it thru the break in.
Ultimately It was not only the break-in, but concerns of later on, motor not being run for periods of time, sometimes driving it in colder weather after spells of dormancy and possibly wiping a lobe. Preventative measures aside I wasn’t up to answering the question “Do I feel lucky”:eek:​
