Re: Cylinder Head misconceptions . . .
Very interesting thread, I wish I knew more about head porting. Luckily, there are people who do and when the amount of labor, material and capital equipment costs are considered, I can't see that head porting is a very easy way to make a living. My hats off to both of the guys posting here who do so.
Thanks for sharing some of what I assume is hard-won knowledge.

I guess you could call me BRESr. except that my connection to Bret's business is that we share floorspace, and I am called upon as an engineering consultant. I have a BSME in Automotive Engineering, so I can sometimes help with that kind of stuff.
I have the good fortune to talk with folks like Lloyd E, Larry M. and a few engineering-types from some of his better suppliers. I am continuously impressed by these individuals, both on a personal level, and on a professional level. Whether it be a one-man shop, or a large corporate one, the folks I'm fortunate to talk with are some very smart fellas. One in particular never ceases to amaze me. It is a shame that he is way too busy to post on these forums. We would all learn a lot.
We have been in the precision machining business for 30 years. Sure we use high-end CNC equipment along with much less sophisticated non-CNC stuff, but it's not just the machine that makes the accurate part, it's the dedicated operator that assures the quality is there. A CNC machine tool will make non-conforming junk just as accurately and quickly as it will make stuff to print. It's up to the human to determine what's good and make the appropriate offset.
Folks might be surprised how some very high-end parts are actually produced. What counts is getting the parts correct. You can BS people, but you can't BS the parts. IOW, a good hand (porting) job beats a mediocre CNC job anyday.
CNC doesn't make it better just because it's CNC. Results count. Anything else is fluff. IMO, that applies to the current topic.
I've been in my share of pissing contests, and I don't think either side "won". We all just had to wash the urine out of our clothes. Nevertheless, it does get things out there in cyberspace. I'm an optimist, you know the guy who thinks the glass is half full, so I think most people take this war of the words for what it is, and have the good sense to make up their own minds.
Hey, if any of you guys who are attending PRI want to chew the fat face-to-face, PM me and we can meet. I really like bourbon and scotch and love to talk over a couple of either. Of course, I also love Minnie Mouse, so I may be at D'World chasing her.

Re: Cylinder Head misconceptions . . .
Quickshot,
I guess you need to speak with AiSr before posting anymore but let me defend myself here. I called from a phone that had my name on the caller ID but never mentioned my name (was never asked) and definitely never gave a different name. I just asked about what it would cost for different heads with certain parts (springs, valves, etc).
I was just curious what parts where used on certain price level heads and what it would cost to get certain parts upgraded. I am not sure what the problem is here. I will give this info yto anyone asking, regardless of who they say they are or aren't. I really ahve nothing to hide here and I am pretty proud of the parts used for the price I charge.
I never implied that anyone told me anything or that more $$$ could be made either way. Just stating what I feel they would like you to believe this. As I have stated a few times today, everyone has their mind made up about what Joe O, Bret, Phil, Ron or I type or say before it is even typed or written. I have respect for all of them but most people are gonna see "their hero" (whether it is Bret, Joe, Phil, Ron or I) in the right and anyone else in the wrong no matter what it posted.
This is obvious by the way people have posted here.

Seriously guys, this thread was great until everyone had to critisize eachother.

I do however agree that some guys will go faster with a little less. I don't think it's ever going to be anything less than ~.45 Mach but who knows what's going on within the port at different areas.

FWIW, Taylor's book was written in the late 30's... I want to say 1939. I don't know if that falls too well into the "trick of the day" category.

I believe the avg velocity was ~320 ft/sec. This coming from a good friend at Ultra Pro.

Like I said,my engines are doing fine and winning some too. I recon I will stay like I am building them
The heads that Richard does for me do just fine the way he fixes them and he isn't using the trick of the day,just a lot of experience on his part.
I deal with other porters also and never had one of them tell me that .5 MACH+ is the way to go and I don't think Richard will either but I will ask him.
On any of my programs it doesn't show on any of the ones that I built to be over .4-.45.

How are you measuring that? Take me through the process.
