The first batch of the RPM aluminum intakes were machined wide and didn't
sit down into the valley properly. Mine opened the valley into the intake
port of one cylinder, and it ingested so much oil that it fouled the plug
and prevented too much enleanment. Soaked the exhaust manifold gasket with
oil and cause it to burn, though (repaired with a Remflex). I used five
quarts of oil in 200 miles.

These were birthing issues long set right, at least on engines that have not
had other undocumented machine work. My second version fit fine and I have
had no problems since then.
