Howdy everyone, I am installing Edelbrock Heads pn# 61779 on my 1999 318cc. Has anyone done this mod? Do I need longer pushrods? What type of roller rockers can I use?

 

idk, but let us know how it turns out. i may get a set myself.

 

I have stgIV Eddy heads on my 408. With .040 crush headgaskets I am using 6.950" long push rods and Harland Sharp 1.6rr.
Old setup with the stock heads and Crower SS 1.7rr and RT+10 cam I removed prior I was using 7.050" pushrods.
You need to buy a push rod checker to find out what length you need

 

Sweet pictures. I had a set of Harland 1.6 roller rockers, but I couldnt use them on my Eddies, the studs on the eddies are 3/8 and the rockers were 5/16. I really want to install 1.7 rollers, but im having a little bit trouble finding them. I had my heads and Magnun valve covers polished, they look sweet. How do I pin up pictures in here?

 

OK I found a pair of Crower 1.7 roller rockers 3/8 studs from Summit Racing. They have two types, one is self alignment and the other is not. Does anyone know what that means?
