intake manifold end seals

Quit using the cork end pieces when I went to Edel heads, they were too thick. Not had any problem, just don't skimp on the application, make sure you get plenty of bead.

Once it's back together, and you find a leak where you did not put enough silicone, it is near impossible to stick more in there and get it to seal, since the oil has contaminated the surface. No need asking how I know.
