[detobias]

cool web site ; yup those look like just the ones I got installed...

my machinist anticipated it would be tough to install these, but it turned out that it was quite easy ..

Ran those for years, there sweet. Many didn't know what they were when I did the conical spring thread first time around lol. The old hat style sucks. I believe mine were for a 426 Hemi.

anything new ???

[lucky13]

Will the PT cruiser lifters, and the conical spring upgrade work on both swirl heads and G heads?

Lucky13: I believe they would work on the swirl heads as well.

I emailed the John at valveseal.com. He said to use the LS1 seal (98-01). Part number VS-805V. Below is the picture. It is a viton seal.


The good thing is that this seal is easy to find at Autozone or Advance Auto (around $22-$24 for 16, Felpro)

I have all the parts ready for my head but the seals. Once I get the seals, I will be taking the head to the machine shop for a valve job and head milling. I am done porting the head and deshrouding the valves. I mostly just removed any potrusions and steps in the casting. I also opened the bowl up a little and opened the runners a bit. A lot of time was spent deshrouding the valves. I also polished up the combustion chambers to keep the carbon from sticking. It should do the job, even if it's not perfect.
