HELP! Header gasket replacement

front and rear bolts go into waterjackets so alitle sealer on them is a good thing,
as for gaskets if the flanges are straight and of good quality i have had good luck with MR gaskets ultra seal.
most gaskets can be replaced by taking out all of the bolts except the end ones the endbolts only need to be backed out alitle and then pull the gasket upwards and slip the new gasket in from the top and you wont need to wrestle with the headers and gaskets at the sametime as trying to find a hole for the bolt
