I buy 4V gasket kit .. intake gaskets only ... I spray the head side with copper coat adhesive .. then stick them to the heads in the proper configuration.... then I center punch the rails about every 1/2 " and then bead it with a nice heavy bead of silicone and bead the intake also .... have the intake ready and slap her on... then quickly bolt here down tight obviously tightening in a spiral sequence and torquing to spec. then with my finger wipe the silicone in front and back.
Always works .. cant say I'm a expert on the theory behind the turkey pan. Maybe George can shed some light on this one .. but I think the old 352/360 truck motors used them also .. the cork and rubber gaskest push out and using silicone only helps it slide out. I remeber those kits coming with a little tube of high tack adhesive ???
My 2 cents.
