Project: BLACK METAL - '67 Camaro

[67rally]

Installed the pushrods, rocker arms and torqued the bolts down today. GM recommends torquing to 22 lb/ft for a stock setup, but with a bigger cam the recommendation is 24-26 lb/ft from many builders. So I went with 25 lb/ft.

With cylinder 1 at TDC on the compression stroke, I torqued down the intake rockers for cylinders 1, 3, 4 and 5; as well as the exhaust rockers for cylinders 1, 2, 7 and 8. Just remember that the LS engine has a different IEIEIEIE pattern than the SBC's EIIEEIIE.

For quick reference these are the drivers side rocker arms you torque down with cyl 1 at TDC on the compression stroke:






And these are the passenger side rocker arms you torque down:




With any ported head, you need to look down the intake port to see if the port work has left the rocker arm bolt holes exposed. If so, you need to add a little RTV to the rocker arm bolts before installing. I added the RTV to both the intake and exhaust rocker arm bolts so my torque readings would be consistent. Here's a bolt showing through the intake side:




And here's the finished product:
