Trick flow noob ?s

Unless you know exactly what you're looking for/at, I would have a competent machine shop give them an inspection. It's cheap insurance. It takes about 30min per head. Mine were excellent straight out of the box. Results can vary. Humans make these, so....

TF provides detailed instructions with the heads. I purchased the matching HS rockers and they really did fit well. Clearances were perfect. Obviously, you'll have to measure for pushrods. Make sure you purchase the correct pushrods for your your motor family!

Also, make sure you match whatever cam-style you're using to the correct the head PN#. There are differences in the retainer types for HR, FT, etc...
