Enlarging PRP doesn't always help

I feel that when it comes to porting, it’s good to let people go down their own path. That way there’s a good possibility of them discovering something you(me) may not have even thought about.

As an example, in the earlier stages of your exploits with the SM testing, you blew that chamber wall out……before it seemed like you did much of anything on the SSR.
Totally the opposite of how I would have done it.

I’m not saying your way is better or worse, just different.
And your results lead you in other directions of things you wanted to test.

I’m enjoying your journey.

Catching up on parts of this interesting post that I read on the run yesterday. I have a little different thinking on helping guys. I’m a self taught head porter that has probably every book out on head porting and never read one. I do have a copy of a Chevy head porting book that is dumbed down a little that I read most of during my Chevy porting days. Even during my two day I bought the recommended calculator that I couldn’t operate and a voice recorder that I recorded everything and never listened to it. But during the 30-40 minutes that we spent on exhaust ports made it all worthwhile because I learned about targeting airspeed more and flow less. There have been days I’ve done 8 flow tests finding tidbits of info but I worried less about manipulating the port but working with what I had. So from going through what I’ve done over the years if I can shorten the learning curve I’ve tried to do it. I’ve been thanked on posts, messages, and even by guys walking up to me at the track. Nobody has all the answers and will continue to debate even the subject on port finish (rough burr finish, double cut finish, or even sanding roll finish). All I can say is make it fun and when you get frustrated take a walk, go shooting, or fishing, or even take a trip to Walmart.
