Plenum Gasket

Hi chaps. I've had the plenum and rocker covers off for powder coating and now putting it all back. I didn't see a plenum to manifold gasket when I took it off - is that normal? I'm contemplating using Hylomar or similar - any comments.

BTW if anyone in the Herts/Bucks area is looking for a good value powder coater I used a firm in Berkhamsted P & R Finishing who came in at a very reasonable £70 for powder coating both rocker covers, plenum, flame trap and MAF mounting/bracket to inner wing - less than half the price of the nearest alternative I could find. After the coating he also sanded/highlighted the rocker cover fins back to the metal all in with the price.
