No worries man. I’m grateful for the assist.
I understand what I need to do.
I just checked the intake again and it’s not .043, and without a different shim set I can’t get to that number. It’s closer to .035” as best I can measure it. That’s with a .040” shim under the intake stand.
On the exhaust without a shim and the lash cap on it, the gap between the tool and the rocker shaft is too big, something like .070. So I stuck a .040 shim under that stand and it’s pretty close to perfect at about .032 - 0.35.
It is a bitch to hold the valve up without a spring on it, whilst keeping the tool square against the valve stem and measuring the gap with a feeler gauge. But it looks like I’m getting there.
Thanks again for your help.
Just for the sake of accuracy, I wanted to report in here that I did a very careful re-measurement of the rocker heights tonight. I discovered that the intake actually didn't have .035” of clearance between the tool and the rocker shaft with the .040” shim under the stand like I stated, but only close to .010”. I have no idea where I got that from. Maybe I confused the intake with the exhaust.
So, I took the shim out and bolted the intake stand directly to the head, and remeasured the gap and it came out to .046-0.050”, as measured with a mini feeler gauge. I made sure to keep the checker tool square and the intake valve up, so I’m sure that’s as accurate a measurement as anyone could get with the tool.
Then I put a checker spring on it, used a marker on the valve stem and rocked the valve open several times as close to the full lift as possible. I used a checker spring on it and measured the open height with a caliper. I took a picture of the pattern on the valve stem, and it looks pretty good to me:
So, it looks like the intake stands are actually pretty damn close to where they need to be without any shims under them, and I’m pretty sure that I’m going to install it without any shim under the intake stand. I’ll check the other head to make sure it’s the same.
Then on the exhaust, I decided that although I only have about .005” between the tool and the rocker shaft without any shim under the stand it, even though I need .033” of clearance, I would try it like that (without the lash cap) and use the Manton instructions to see where the roller sits on the valve stem at closed, mid-lift and full open.
The weird thing is that the sweep on it looks very close to what I’m seeing on the intake. So, although according to the T&D instructions, the stand “needs to be” lower, the sweep across the exhaust valve looks pretty damn good anyway (according to the Manton diagram). So, I’m wondering now if I shouldn’t run it like this or whether to use the lash caps and shim the stand to get the desired .033” clearance?
Here‘s where the roller tip sits with the valve fully closed:
And here’s where it is with the valve fully open ( I measured the open height with a digital caliper):
So, since I’ve ordered a bunch of shims, some .060 lash caps and the recessed locks, I’ll check the sweep again with the lash cap and some different shims once I get those things, to see if I can get as close as possible to the required .033”, but I’m pretty sure I could just bolt these damn exhaust stands on without any shims under them and let it eat without any problem.
