Rettedm Posted November 2, 2014 Posted November 2, 2014 Reinstalling my 1700 supersprint crossflow head after valve job and have a few questions for you experts..... Re-use stock head bolts or new? If new, Stock or ARP? Oil on head bolt threads or dry? Will Hylomar be sufficient to seal intake gasket? Does the stud in the center of the intake bolt pattern need to be sealed? (does it enter the water jacket?) Any other tips? Thanks! Dave

Does the stud in the center of the intake bolt pattern need to be sealed? (does it enter the water jacket?) New ARP bolts are cheap insurance, especially if you don't know the history of the existing ones. Never oil threads, they varnish and seize. Use "never-seize" or "copaslip" compound instead(but don't mix the two!) Hylomar on the intake gasket is a good idea, and the center bolt is blind, so no seal required. Most guys blank off the center water feed to the intake manifold anyway, its just there to help prevent fuel icing in the original street car applications. Unlikely your 7 sees temps that cold?
