Leaking Intake Gaskets ... bolts loose
regular steel single edge blades and/or good penknife fine on those tough iron heads & china rail ... use a bit more care on aluminum manifold.
If you're Not subject to NCRS judging ... and have time to get em ... a set of new intake bolts in the "reduced head size with 12-point" version makes it a lot easier to get to & tighten them ... a dab of permatex #2 or rtv on threads helps prevent oil creep. Don't use stainless bolts.

First, it's not an edict but advice; do with it as you wish.
stainless looks great and may be called for in a marine environ or desired for "show car bling" use.
I suppose finned aluminum oil pans, and chromed oil pans & timing covers are great sellers for Spectre as well.
but stainless tends to gall under higher torque (noting intake is not hi-tq) and is relatively soft.
for most external motor apps, a good grade plated steel is preferred by many builders.
That's my tale and I'm sittin' on it.

So I just got everything back together tonight and fired it up. It seemed to run about the same so I decided to attach the vacuum gauge to see if it would read any different but it unfortunately it still jumped around. So I decided to test other vacuum ports (I was currently hooked up to the head light vacuum source) so I attached it to the pcv vacuum and still the same jumping. So finally I attached it to the brake booster port and it only slightly moved around about +- a half an in of Mercury so it seemed better. After noticing this I thought my problem could be that the brake booster has a vacuum leak and I already thought it did before all this based on other stuff but anyway. I plugged the brake booster hose so it was out if the equation and tried measuring off the pcv port again but the same jumping happened this time too. so what do you guys think it happening here?

Pro
See post # 3. Potential valve guides. I would do a leak down test at this point to verify before you pull the heads.
