Well now going to get heat back on..it is remarkably straight and no warps…I cleaned it up and discovered the torque on the old gasket cut an indentation into the head…I can feel it with my fingernail and worried the new gasket will leak…got it cleaned with razor blades and would most likely have to sand the grooves out…..I don’t want to ruin head by sanding and wondering if I should coat the impression with some type of sealant before installing gasket} thanks for any help[PROCESSING IMAGE.... PLEASE WAIT]

Just get it as clean as you can. I would not sand it. It's important to get the block clean as well, and get it clean right up to where the studs screw into the block. Don't leave any crud around the studs where they meet the block. Follow the correct tightening sequence and tighten with a good torque wrench in 3 stages, and re-check torque after the engine has been run and allowed to cool down. I've had good luck on flat head engines using conventional type gaskets using spray on Coppercoat gasket sealer on the gasket itself. All threads need to be clean and lightly lubricated.

Great thanks…I do have conventional gasket and bought the copper spray the other day..head is cleaned well and have printed out the torque pattern ….appreciate the information..I will install tomorrow…!!
