Thats about were I am at with a set of DOOE heads and a .500 lift cam.

Have ported E7 heads that pulled 375 HP on a chassis dyno but test was stopped around 4000 RPM due to need for larger injectors.

My friends shop I worked with porting heads worked for Batton for years and got to learn more about the effects of different cylinder heads mods than most all of us. Batton owned their own dynos and at one time did most of the big threes experimental cylinder head work.

492 lbs-ft at 4000???

Sure it wasn't 275 hp for 361 lbs-ft at wheels??

You got some BS results then. You weren't making that kind of power. Unless physics no longer holds up.

Update, my competitor has his E7's tubed and 8 angle valve job done, some Pitot work and finessing is all they need. This will be a fun test.
Thanks, Charlie

If I already had a good usable set of stock heads and only had to port them my self I could see it, but I also have a $1500.00 SF110, a $450.00 Fordom grinder along with a Makita hand held and several years of screwing up heads... If your looking to learn how to do it yourself for future projects then using DV's writings is the way to go but it will cost you to learn but it's money well spent.

I would personally recommend focusing money on tools and "how to" education and save parts modification for later.

With that said, I also feel confident that I'm more skilled than I was the first time I ever attempted a porting job trying to port an aluminum iron head with an air powered "dremel" type tool from Harbor Freight using a tiny double cut burr meant for steel.

I've gotten a lot of education in my lifetime, and pretty much all of it has come at some sort of cost, be it money, time, trashing otherwise good parts, etc. If you're trying to learn this stuff, you need to be willing to accept the fact that you're not going to be perfect the first time you do it, and you'll probably end up ruining at least a few pieces of whatever you're working on. If you don't care to learn it, if you don't enjoy the countless hours sitting in the shop doing it, if you just want to reap the benefits, then save your money and don't buy the tools... pay someone else to do it.

Personally, I like doing things myself, even if I'm not the best at it. There's a sense of accomplishment that I enjoy. I'm well aware that I could ruin a part any day, and I really hope I don't, but if it happens I'm willing to accept that and move on, adjust fire, and figure out my next solution. I can't imagine that Smokey Yunick, David Vizard, John Lingenfelter, etc. was born knowing how to port heads/intakes. Everyone has to start somewhere.

If you approach everything like you know nothing then you will learn something.
It all starts with a passion to learn so you can hopefully obtain the knowledge to share.

Wonderfully said. Sometimes I wish the second part of that statement could be utilized rather than hidden by a lot of guys who have succeeded in "going fast". Not so much on this forum, but on others, it seems a lot of times people would rather brag about how well they did rather than tell you how they did it. At that point I can't help but wonder why in the hell are they on a forum in the first place? Aren't forums places for people come to ask questions and learn?

I know what I know. I know what I don't know... and even worse, I have no clue about the things that I don't know I don't even know about... haha! Wrap your head around that one. :D

After a small setback my competitor let me know these will be the last set of E7's he will ever do! Can't blame him a bit!

Hopefully not a water sprinkler type of setback. Those kind really suck!

Like DV said when I told him I made a sprinkler system out of his 289 head. "If you didn't grind a hole I would have said you weren't trying hard enough!".

My competition sent me this pic and stated, "The gloves are off with these things!" I say, " Be careful, I know they are thick but they aren't thick everywhere!" That machine is on my wish list no doubt.

I think you would either ruin your pants or cry if you saw the centroid working up close and in person.

NICK-- YOUR COMMENT --Personally, I like doing things myself, even if I'm not the best at it. There's a sense of accomplishment that I enjoy.

I am with you all the way on this comment. During my life I have had some world class mentors. A lot to be thankful for.

I've had a few of those myself. You might even know one or two of them. They're unlike you in the fact that they don't go onto forums and aren't quite as public, so I'm not going to throw names out. They are getting up there in years and (I'm only guessing) probably don't want to be inundated with a million questions, emails, phone calls, etc. As these guys slow down I'm trying to get myself introduced to new mentors (hint, hint :D )
