Trick Flow 440 heads, The Real Deal?

RustyRatRod said

Talking to a good friend of mine he pointed out that these heads will likely need longer pushrods. He said to get these flow numbers, the port roof has to be raised and a valve over 5" is probably used. That would require the shaft support to be raised as well, requiring longer pushrods, right?

Tomorrow, tomorrow, I love ya tomorrow, you're only a day away..............

Mike could maybe tell us today if they are using a longer valve.

When they get here tomorrow I will measure from the deck surface to the rocker stand and we will know. But I can tell you this, we have gotten, according to our flowbench, 350 cfm from the RPM head and the Stealth head and they don't have raised ports.

Of course these heads will give us an idea if our flowbench is all out of whack. We can compare our bench to Mike's and the advertised flows. So far no CNC ported head has ever even equaled the advertised flows when tested on our bench.

You cannot race flowbenches.............but you can compare different heads on the same flowbench.

Tomorrow..............
