I'm happy to do that, send me a PM to discuss.
It shouldn't be a problem to remove them, you have to be careful lifting them off, if you lift them off on an angle they can crack where the pins go in. It's important not to use too much gasket marker putting them back on, since it can overflow into the oil passages and block them, apart from that it should be fine to remove and reinstall them.
