word of advise go ahead and put time cert in the center head bolt holes located under the valve cover and get 2 grade 8 allen head bolts to install in those 2 holes these always seem to strip no matter how careful you are when installing, nothing like having the head on and tightning the 2 center bolts only to have them strip !
