Yes, I believe you understood me correct. I know of several shops including my own that stand behind our work. Sometime "stuff happens". I always ask myself, who did what wrong and try to work out a solution from there. Most of the time all parties involved realize if they give a little, it turns a crap situation into an acceptable one. Sometimes the manufacturer will step to the plate also. Holley was willing to work with us on an engine that had a melt down because a Q-16 carburetor was ordered and a race fuel carburetor was delivered. Not sure what current pricing will be on Edelbrock heads. I've had a pallet full on order for twenty two months and we haven't seen them I'm being told January... Which will be an even two years. The FB link at the bottom of my post will take you to my shop.... You don't have to be a member. |

Sorry for a confusion with my posts in regards to my opinion on SM heads. They are what they are. I made a thread trying to convey that. They're probably a bargain at Holiday pricing but a slap in the face to their dealers. I pointed out in the thread I started about them the major flaw in the casting that limits their power output. I bought a set I wanted to try on a 446 CID nitrous engine. They have a feature that would probably help power output on a stock block build but after looking at them and reading the supplement warning about porting the heads may cause the valve seats to fall out I put the project on hold. I have three options, fix the flaw, run them and keep my fingers crossed or use them for a different build.... But I never meant to imply they were garbage.

To me when i hear the word blem i think cosmetic and cosmetic only, NOT a high probability of a failure point a miss cut seat area is a manufacturing defect to me out of spec pocket for a seat to be inserted
So your definition of a blem No i would not buy but purely cosmetic i would consider blemish blĕm′ĭsh noun A small mark that makes the appearance of something less attractive. An imperfection that mars or impairs; a flaw. A defect, flaw, or imperfection; something that mars beauty, completeness, or perfection. The American Heritage® Dictionary of the English Language, 5th Edition. That definition is more about beauty than function . Last edited by Formulas; 12-02-2022 at 05:22 PM. |

Well, since the seats being correctly installed is the most important thing on a cylinder head preventing catastrophic engine damage. Nope, its a time bomb.
I even had my High Ports ordered without seats and guides so SD could do the work. |

That's how I feel. Plenty of new heads have dropped seats, so saying a blemished head might drop a seat isn't anything I'd worry about too much.

Occasionally there will be heads for sale that have some porosity in a spot or two and they are sold as a blem head. You know up front there will be welding involved to get it ready, or has already had welding done.
I have had a seat fall out of the head from getting the engine hot on a 454. I didn’t save much of anything. When you build an engine you never plan on over heating it. For me when the seat insert is what makes it a blem. I am wanting to scream. RUN FORREST! RUN! Last edited by Jay S; 12-02-2022 at 07:34 PM. |

Repairing a seat in a head isn't a big deal, Machine shops do it all the time.
I bought a set of new bare ED heads and one seat wasn't seated all the way. My machine buddy fixed it for me on the spot. If the problem was that bad I don't think it would be offered anyway. My self I would buy them. GT |

Here is my deal. I do not like the fact that I have a crank and a set of rods that originated in China, even if they were machined here.
American iron is a good goal to have. I have 2 sets of American aluminum heads. One with extensive porting and the other with mild porting. The High Ports with the mild port job will at some point have a extensive port job. I am all about the port work. If I can not have a real port job done and have the head structural integrity of the head intact, I will not own the heads. But for the guy who wants a 500 HP cruiser I am sure the SM heads are fine. Myself, if I am going after 500 HP I would run iron heads all the way. |

I think that if the SM’s were a d port at this price point, they would be the ****.
It’s easy to spend more than the SM admission price fixing up 50 yr old iron heads. Buy them bare, then set them up with good parts & roll but I could be wrong . Murf |

"Blem" heads from a top-flight manufacturer, AND it does not involve seats falling out, or faulty guides? I'm good with that. (i.e., cosmetic problems, not functional problems.)
"Blem" heads from a bottom-feeder company? Hell, no. Their "good" heads need rework, I can't imagine how bad the "Blems" are. Seats with improper press-fit are not "blemished", they're junk that needs total rework. By the time you pay to fix the seats, and the valve-job afterward, you shoulda/coulda/woulda bought decent heads from a REAL manufacturer instead of dirtbag "aluminum butchers".
