trickflow heads

My fault. I cheaped out and bought them because they were cheaper than AFR or LPE heads. Thought it would work with a LPE short block. Saved a bit too. Good thing. I spent the savings on a new short block. How cool is that.
The new short block was being built and I had the heads sent in to be looked at. Builder called me to come in and look at the heads. Driver side was fine. All 8 valves in the passenger side were loose and wobbling once the spring pressure was off. I got it fixed and sold the damn things.
If I were to ever buy a set of TFS heads, it would be bare and I'd have a good machinist go over it and load it with hardware of his choice. Probably not unless I absolutely had to.





But since they are local to me, I got curious after reading this thread.
That story sounds like a young company with young/inexperienced, or low paid, not interested help.
Or help that is being pushed to produce and get products out the door. Or a company working on the edge of cheap in order to out sell the competition. After all, if you are selling your own product, you are keeping ALL the profit.
Summit Racing (TFS) is 18 miles from my house, they advertise a lot for sales help. Hopefully they retain manufacturing personnel better than sales.
Here are 2 articles I found about them, as you got me curious as to how junk like you (aklim) had got out the door.
I also found quite a few instances of quality issues on the web. Most were back in the 2002 time frame, but I did find one from 2014. I didn't join that particular forum just to be able to see the pictures, but the comments were a bit sad.
With the bad press that I saw, if I bought a set of them, I would have them checked over by a competent shop. The price to have them checked is small compared to an engine. Even if it turned out to be 1 set in 1000, knowing that there could have been 999 folks buy before you did is a bit unnerving.
The date of the 1st article is in 2011, the 2nd 2014. Machines that are shown in the 2nd cost money. A lot of it. A lot of product needs to be sold to pay for them and the building in Tallmadge, as well as pay the staff.
Now that I know that they are running a manufacturing plant there it explains the massive A/C units I saw being installed and the equally as big portable generators that running them last year. I asked and was told that at the time, there was not enough power available yet to drive the A/C units.
It seems that they recruited some more talent in 2011.
As an aside, I was collecting and restoring a certain brand of shotgun that has been around for a long time in this country. The original company went under due to a buyout and mismanagement (profits were bled purposely). The name and rights were bought and now they are produced here in Ohio. I have toured their shop and they have had similar QC and growing issues, even with all their high tech machines.
It takes a real commitment to be able to throw a scrap/marginal part in the recycle bin instead sending it out the door with fingers crossed.

afr heads were also available in a wide range of cc sizes - which enabled me to safely lower my compression (the right way vs. domed pistons)
