do i need a sealer or some type of loctite ? the intake stud hole is drilled into the intake port i've always used sealer before but that was on iron heads this is the first time using aluminum heads and is there any other tricks when using aluminum like anything on the header bolt threads ?

I used a little dab of black rtv for the rocker studs and nothing on the header bolts. However, I used copper rtv instead of header gaskets.

Its the kaase canted valve heads for the small ford they have 247cc intake runners with 2.10-1.60 valves and the flow is supposed to be 345-242 @700 lift although i havent had this pair flowed yet. A guy on the nmraracing forum had a pair he sent to kaase for some porting and his flowed 365.
