It's funny how some people say their ported heads are better than Champions but the facts are Champion iron and aluminum have the best times out there period ie: Roy and Laz for irons and Don Cruz for aluminum. Tom produces a great product at reasonable pricing.

.....snip......I do agree that flow numbers are not everything. Tom has proven that higher flowing heads can actually drop power. The secret to any motor build is getting everything to work together.

It takes a lot more than a flow # to make the most power with a cylinder head. More flow doesnt mean crap.
My iron heads are from Dan Strezo at DLS, been 9.30's at 144.
I respectfully disagree on the higher flowing heads can drop power.
If you look at a heads flow at all the common lift numbers..... .200 , .300, .400, .500, .600 etc..... and if it flows more air as compared to a lesser head...... the potential is there to make more HP period.
If you don't pick the surrounding parts to work with your heads..... then it is on you....
All things considered..... higher flowing heads will yield a higher potential HP everytime.
Bison's comment about it taking more than flow to make big power is true to the extent... that you have to pick the right combo of parts..... and have the right tune.... to make the big power. His main point was that just having high flowing heads is not some magic pill to make big HP. The fact is.... if the person with the better flowing heads.... put the right combo together with the heads.... and tuned the car right (chassis and engine/tranny/gearing)..... he has a potential to go quicker.
You don't see the front runners in TSO running poor flowing heads..... cause they will get their @ss handed to them if they did.
I basically said what Bison said with respect to getting everything to work together.
No problem with disagreement about flow can hurt. I am referring to replacing set A heads that flowed 200 with set G heads that flow 400. That can very well drop power. With your disagreement, you actually agree with this logic with your comment that you build a motor by picking the right combination of parts. Now if we are talking heads A and G on the same motor, then G can result in less power. That is my point.
ind you, my letter and numbers are only for reference. I do not want to confuse people like I know a lot, just enough to begin to understand a little.
Again, it is about matching parts that compliment each other !

As far as the OP’s question:
. . . . . but on a turbo car, you have to determine how to deal with the physics of the reversion/BP to maximize VE.
