Mild, you have a desk top dyno program, would you be willing to punch a couple different combos in? It is winter now haha and I am quite serious about head upgrades. If you were willing I can start a new thread as I'm sure others would be interested.

I do, and I also have a dump truck! PM me your email and we can talk about your setup.

40 man hours just on the combustion chamber design..I love my head guy. No mass produced product can deliver quality and attention to detail like that.

I agree 100% Dan! Until someone gets to experience this type of work first hand and the benefits it yields, they would never use out of the box again. I make sure that I take care of my cyl head guy and his employees when he completes the maintenance on my heads!

^^^ agreed 100%


Anyone near Chicago Mike @ High Flow heads is one hell of a guy, honest as the day is long and 30+ years of experience. I`ve used him for more than 15 years and been never disappointed.

u gotta love the sharpie as his blueprinting dye
and do agree after 40 yrs of being around motor builds
very few hard parts are used out of box for a good build

I’ve really been getting into (kind of forced to) heads this summer and fall (was working on a set today). Well, big block Chevy heads since that’s what I have on 4 motors. I now have spring pocket drill bits and auger, valve seal bits, measuring tools, straight edges, lapping tools, assorted shims, homemade head stands, homemade triple spring compressor and an assortment of porting and polishing tools from my Dremmel to air die grinders and a number of metal files.
I use to just bolt on like a lot of folks and I can see why because I have been collecting tools for years and don’t have anything even close to what the guy does in the videos. And it seems like I’m light years from the bolt on and pray days but along with not having all the right tools, I still don’t know crap. Lucky enough I bought a couple sets that were both ported and polished by Crane and Mullen & Co so I got great examples on what porting and polishing is supposed to look like. Spent a lot of time on-line learning about lapping valves and how it should look when done. How to measure keeper heights, the compressed heights, the seal height and how to cut new if needed. About standard, over size and undersize keepers and standard, over size and undersize locks, 7 degrees, 11 degrees, steel, stainless steel, titanium …. Ugghhhh!!!!
It gets a little overwhelming and I can see why most would rather just leave it up to their machinist. But I wonder how many do what this guy does? I have a hard time just finding someone that will put a valve guide in. I guess that’s why people ship him stuff and brand new stuff at that. Shame it has to be that way.

The video says it's a Tom Rockwell race car production, but it looks like the presentation is by Mark Jones/ Vortec Pro. So does anyone know who is actually in the video and what sort of reputation or motivation he has? A quick glance at the search results for those names showed me a basic website for Rockwell and link to a yellow bullet thread where Mark/ Vortec is being called out as a scammer in a very long winded post that I didn't care to read. He has a video about cracked/ damaged valves in a head manufactured in 2006 in a video dated 2013. Says it's only been down the track 70 times. Who knows? I've got no reason to disbelieve him, but I've got no reason to believe him either.
