felpro headgasketca18det

During my headgasket replacement, the part when you put the headgasket on then the head on. Both block and head surfaces were clean, then I tilted the head on it's back (firewall side) so I could clean the bottom up one last time. I then put it back down on my table on it's mating surface while I sprayed the HG and cleaned the block. I installed the HG then the head and torqued down bolts once. Wasn't planning on unscrewing and re-torquing.

The head surface was completely clean, but after I tilted it back and then back again some oil must have moved around, because i saw a little oil on my table where the head was sitting. Oil was on the exhaust side, at the back of the head. A small bit, and the head was on some plastic so i'm hoping the plastic took most of it.

Does anyone know if having a little oil on the head before clamping it down to the block is bad? I'm thinking about loosening all the bolts, lifting it up a little and cleaning the gasket.

Any recommendations are welcome, this sucks!

it's felpro from advance autoparts, def. not a metal one. Whenever I remove it, the head and block keeps a bunch of grey metallic junk on it that I need to scrape off.

I guess the big question at hand is, is it ok to remove the head after being torqued, but not ran, and clean the area between the head and gasket? I can probably pull it down on the corner a little and clean it without changing the position of the gasket relative to the head, but i cannot guarentee the same regarding the gasket and the block.

sigh this sucks, id rather drop $50 and get a new HG and do this now vs. in a few months and take everythinggggggg of again.

Just take it off off, clean whatever it is you want to clean, re-install it, and re-torque it (No harm, no foul).
