Hey guys,

Since I am replaceing my valve cover gaskets and have the valve covers off, I figure I might as well torque my head bolts. Does anyone know what they should be torqued to? It's on a chevy 350 with World Sportsman II heads. Thanks!

Thanks for the link, but I don't see that many bolts to tighten...do I need to take off the intake manifold as well?

 

9 are under the valve cover and 8 are below the exhaust ports. Unless you just put the heads on recently, I wouldn't mess with it.

 

there are exactly that many bolt on a sbc head

#s 1,2,5,9,13,17,6,10,14 under the valve cover
#s 3,4,7,8,11,12,16,15 are along the lower outer head under the exhaust manifold or headers

 

Hey, i am replacing my bolts and found the sequence here, but There are 3 lengths of bolts, i know the longest should go up top and the shortest goes on bottom, but there are 2 mid length bolts. Where do those go?

 

the mid length bolts would go into numbers 17 and 14 in the diagrams posted in this thread.
