I never met a project I didn’t like
Perhaps a new 'What are your lingering projects?' thread is in order......

Are you trying to make me write my biggest post ever?!? haha
I loaned out a oil priming tool 1 1/2 years ago, no deposit, I paied to mail it with the word it would be returned along with 10$ for my mailing cost... he must still be priming because it's still gone... and it was someone here as well... so I made a few more for more respectable folks to borrow...

@n8in8or
Digging this up because my new heads are on their way. I’m trying to figure out diy on mine.
I noticed you used tubes with 1mm thickness.
The L&S ones say they are 0.050“ thick which is 1.27mm thick. Mighty thin difference but percentage wise is a decent amount.
I wonder if that was part of your fight?
I also wanted to know what was your final outcome with this. I can’t remember if you did this to your hot rod heads you ported and outcome how they affected it.
I know machine shops push milling the head for any reason ($$ perhaps?) but I cannot imagine adding these could cause any dis formation in the head. Did you do a full set and straight edge afterwards?
@Twisted Steel Performance on your P400 heads where you added the fittings to the manifold to eliminate the trapped steam pockets- did you add the inserts in yours?
Also- I use my phone for TTS- don’t even own a laptop or desktop anymore.
Opening pdf is a pain when I can figure it out and currently can’t.
Is it possible someone could open the pdfs and screen shot the instructions and post the picture in full size not thumbnail for me please? Idk how monstrous the files are but I imagine not more than a few pics each.

P400 heads are thicker and the passage is their but has more metal, and they aren't induction hardened so they aren't likely to crack ever, so their is no reason to do this mod on p heads...

I’m looking at it as an insurance action.
iirc the ProMaxx aren’t induction hardened either but use hardened seats- and those crack still. A couple hundred bucks for the biggest known failure point on 6.2-6.5 heads just seems no brainer to me. Without me knowing it, the ol Machinist that did heads for me used to do it automatically to all the 6.2/6.5 and ford 6.9/7.3 idi heads. It was just wrapped up in the cost of him going through them. He passed away some years back.
I called other machine shops around and most never heard of it even.
Hearing that from you is peace of mind that if I can’t do it I shouldn’t panic since I have the p400 heads on the way.
But is there something you saw that would outright discourage you from doing it?

Oh, the Goodson kit from the past is
BL-3900 but is nla.
In their 1999 catalog is on page 67. Any other information they can dig up, he will email me. Even if I don’t use it info might help someone else down the road.

Trying to remember back……I believe I found they already had the tubes installed in that set of heads, but it didn’t matter as I ended up with cracks and steam. Perhaps the cracks in between the valves weren’t steaming, but that big crack in the throat was.
