spark plug adapters

Does anyone know where to get a set of adapters that will allow you to run a 14mm spark plug in the big plug (18mm) DOVE heads?  I saw mention of Garrett machine when I did a search, but am not having any luck.  

How do these said adapters work?  Will I need a longer reach spark plug than the conventional .460"??  Any help is greatly appreciated.

Thanks,
Jon

Garrett made the only ones that i've seen.

After doing some checking around ... I was told that a company "Innovative Products of America" has their version of those adapters.

AND, available through Advance Auto Parts.

Thanks for the info! I'll check those out from advance auto.

Looks like I found the ticket!

These guys have just about any adapter you could think of!  The best part is the price @ $5.65/ adapter vs. ~ $15/ adapter from advance!

Garrett is where I got my set. Not sure what is up with their main website, but you can hit http://garrettmachineandwelding.com/ to get his number.

WOW $15 bucks apiece is a bit pricey   

Think I'll stick with my 45's

It is about right for a double threaded, lathe cut product not CNC machined in the U.S.A.

LABOR is the main area where you get what you pay for.

MAYBE you have to call them but I don't see an 18mm tapered seat to 14mm flat seat adapter in the bunch they show.

Yeah Randy..

I ordered a little pre-maturely.  I ordered his 14mm to 18mm adapters and then realized that the adapter was for a 14mm tapered seat plug.  

So, I sent the guy an e-mail and he called me with-in 30 minutes...  Keep in mind this is around 8pm.  He was great to talk with and told me to just send him the plug I wanted to run and he would do his best to get me an adapter built!

The problem he kept bringing up with the flat seal deal was:  In order for the adapter to have a hex, it would need to be fairly long and that could throw a wrench in using a .750" reach plug.

-----Do the garrett pieces have an external hex to install them with, or do you just use the spark plug to install the adapter?

The ones I bought from Garrett machine did not have a hex on them. They come with a tool to install them and instructions to use a specific Loctite when installing. They worked great but after several heat cycle would sometimes come out with the plug when changing plugs, was no big deal to get them off the plug and reinstall.

That's just the info I needed!  Thanks lghting94!  

What did the tool look like?

a machined sparkplug section with the threads and hex head only.
