Looks good to me and would be a good mate to the cam you got from me. Put it with a down draft 2V on it, a header, and I bet she'll run nice. Most likely not real good to go slow with

Well, if you look at the intake valve to plug pocket, the head with the nice port work has much larger valves. It also has a stainless wire o ring.
The valves are seated higher on the head in the first picture, rather than sunk in as on your second picture. This allows the valve to start flowing earlier and improves flow at low to mid lifts. Again, much more experience in the top picture. Look at a fine example of a venturi effect in the cuts under the seat angles in that first picture. |

Does every Southern Machinist use a rusty framing square to measure? That's a dandy right there....

Dividers are used for scribing lines, arcs or drawing circles set with a scale or rusty tape measure and used to transfer that measurement to your work |

How are we supposed to critique the port work Pank? By how shiny and smooth it is? First job given to an apprentice in a Iron foundry is grinding away casting flash. Looks like you passed first day die grinder at the foundry. I can coment on the valve jobs. The person who preformed the seat work on the first head has played around with a flow bench and knows that valves flow best when seated high,either that or he was just lucky and that's where they came out how would I know? We were taught even in trade school that a person doesn't want to sink valves such as was done on the head in picture #2 as it will affect flow even on a normal rebuild, let alone performance applications. Next time Pank give me a shout as I am tooled up to install seats and can bring those valves back up to the correct height for you. Seat work aside I have no opinion of the work. Shiny appeals to Crows and Squirrels but gains nothing in a port. Big impresses the girls but doesnt directly translate to HP out of a porting job either. I have seen some fancy looking work that didnt build power. How much power was made with the heads at what cubic inch? What did they flow on the bench?
As for what they look like in a picture? Who cares.

I guess you don't know SQUAT about measuring tools either cause the inside and outside measuring devices you are talking about are called calipers. Description6" Inside and Outside Spring Calipers are a shop necessity for measuring inside and outside diameters. Often space is too tight to get an accurate measurement using a scale-type measuring tool. The spring calipers allow the user to transfer the dimensions of a workpiece to a scaled device. |

A person must learn in steps Ken. Remember the pulling hitch build, rear wheel cuts and oil cooler installation photos? At least now they have acquired SOMETHING to measure with When they clean the rust off of that square they will be able to direct read in 1/8" increments and if they can see good they can eyeball down to a smidgen or maybe even a hair.

I'm not really sure what the display of a Union Logo has to do with anything, I've known many guys that I would be proud to hold the oil can for that never had a Union card. If we are going to show logos, let's do it attached to an item that stands for something. Here's my logo, attached to my diploma and dues book, now let's see what Pank and mgburchard have to offer since they started this, another challenge if you will Gents??
You don't get one of these pretending in the backyard or your Buddies shop, you either have it or you don't, since you claim to have Union status of what you know, lets see it... I'm guessing it's going to be like the Gleason.

Because silly games is the primary reason you are here to begin with Pank. Such as why post a picture you took from Marty's facebook page and post it here without saying so? Too bad the ploy didnt work. The Experts work got picked out As did the wannabe's Where is the two wire Gleason you claimed to own and operate? Liar
