I have 88 5.7 small blocks with full closed system.I replaced the exhaust on the port engine last summer.this week noticed a coolant smell when staring cold.removed the risers and the gaskets were crap.the store only had the osco gaskets last summer so thats what i bought.I just purchased the merc gaskets.what was in there originally had a stainless plate between two gaskets.the guy tells me the new merc gaskets don't use the plates anymore.I was going to put the plates back in with merc gaskets but can't find the plates anywhere.Is it really Ok to just use the merc gasket?Just want to make sure.te gaskets are full block off because the manifolds are coolant cooled and the risers salt water cooled.Thanks
