W5 stuff

I just talked with a mopar perf parts guy in SC & he said Mopar Perf dosent stock valve seals for w5s anymore , My heads have that small under .500 guide dia , might be .498 or so , I cant remember , Any body have any luck finding them? or am I the only one running this guide dia.

Do you need SEALS or GUIDES?

I don't think MP ever sold seals, but I could be wrong.

W5's from factory use a .494" guide in a .492" hole. 3/8" ID with a .531" seal area..... so a factory W5 would just need a normal 3/8" .531" valve seal. You can get those anywhere....

The valve guides are a pain...... normally we just use a core reamer & ream the guide holes in the head to .500" & put normal .502" guides in them.
