Hey chilly460, regarding spring loads...

When I'm not logged in, I can read your last post.  When I log in to answer, the page has an error.  Not sure what's up.

But no, 170 is not too much.

I couldn’t get to it either, didn’t think to try not logged in. FYI I don’t do it as a stack, I zero the height making the machine read the installed height and double check by setting the spring micrometer and measuring it

Be sure to measure ALL, you may find some short or long installed heights and some variance in springs.

Ahh, I was having the same issue, I’ll log out as I was in the middle of posting when it went wonky.

I have the same issue on that post, and on the SOHC heads with the cracks. It only shows the initial post and no responses. Weird. I also didn't think to log out.
