Had it 2 weeks I,m a rooky but Know my way around a shop a little , I think there called plumbers , do they just unscrew?

 

Yes they do you might want to convert to the o'ring style intake manifold system Much much better J&P shows one P/N 401-635 made by Colony or try the silicone first Clean the manifold and plumbers fittings (brake clean ) wipe the silicone all around the area let it sit overnite then see if it seals better I'd convert it my knucklehead has the conversion Good luck

 

Thank' for the help ,I'll try it this week end.
