In my case, I've got the equipment (porting tools & flow bench), but doing it myself always stretches out the time to completion a lot.

Dwayne Porter mentioned once that he thinks I like the R&D aspect of this stuff as much or more than the final results. He could be right.

better get a flow bench

I've had one since about 2000 and have posted lots of flow test results on here over the years.

What I don't have is a full-time porter's experience in getting the best from a set of heads. It's all R&D for me once the basics are covered.

I just bought and read David Vizzards book, How to port and flow test cylinder heads. It gets real deep into head porting,building a real cheap flow bench, along with a whole lot more on what makes horsepower. There is info on fuel vaporization, swirl, tumble, and much more. The investment in your case would be a very good match. You might improve on what you have as well! By using foam rubber to cast the porting you have now, and transferring it to a plaster cast, you could mess around with it a lot before getting out the bits to do the actual heads.

I use to have a cheapo home made flow bench but I
sold it and am still looking for a newer bench... at
work we used a liquid rubber product to make molds
of the ports so it was easy to measure or do other
things from the plug.. even making a molded port

I may have missed something, but just what R&D have you been doing ?

---

It's usually just been stuff for myself, such as improvements from head porting updates, testing self-ported intakes (dyno and/or on-track comparisons), cam & rocker ratio comparisons, etc.

I've done flow testing of various heads & intakes over the years for some different Moparts members (usually local to me, but not always), too. A lot of that was 'cuz I looked at it as a win/win situation where people got their test results cheap and I got to look over different heads and increase my flow test reference data.

If I'm trying something new or different, it's ALL R&D to me.

We wouldn't be racers if we bought everything or paid someone else to do everything,we would just be another driver.To be able to challenge yourself with projects is the fun of it all and with every accomplishment comes the pride.Even when project goes bad it isn't a failure it experienced gained.

VERY TRUE Bob.... and lately I've been gaining experience.. LOL
