That's been a few years since the heads were off. At that time the heads had about 9-10 months since a total rebuild. 596 heads. I took the heads off and ported for a few days (under shop instructions). They did a couple hours of touch up and put in 2.02's. Oil leaking in all 8?
I haven't heard any leaks...
If the guide is leaking it will pull oil out at idle. Its not going to be enough to see smoke out the pipe, but if it is it will eventually throw a puff of blue at startup.
I don't think it is something to focus much with at this point.
