Heads for 440

They all serve their purpose. The Trick Flow on my 505 and made over 600hp with a hyd roller cam so what is not to like!?

The source are cnc ported and even though I bought them second hand they really woke up an 8.5-1 440 with a comp XE274 hyd cam.

I have had edlebrocks before and they were an improvement over ported iron heads. The set I have now is cnc ported and bought second hand in need of repair. I look forward to running them once one chamber is fixed and new valves installed.

Trick Flow were awesome out of the box and needed nothing.

The source needed the valve guides touched up but have been great otherwise.

I would take my (MCH) cnc source over a stock Edelbrock.
