Crane Gold Race Rockers on a 3500 head

[SappySE107]

As some already know, the raised ports on the 3500 heads cause a clearance issue with the pushrod guides. I have modified the head to accept the guides and now the crane rockers or any other that requires pushrod guides can use them.

I have 2 sets of the crane rockers in 1.6:1 that will be sent back soon if they don't sell. For those that want to use them on the 3500 heads, now you know they will fit with work to the head. It doesn't create a problem for porting either, since I tested it on what I will consider a boost oriented porting.

what did u do to modifiy the head??

See where the guide goes across the port area on top? That was all ground down a lot so it would fit.

ben, would it be possible for CNC guy to rig up some 1 piece guide plates?? as in the plates for each side of the head are all once piece, which would than act as a stud girdle... i guess the plates would go over the top of the head bolts but the rockers and plates must come off before removing the head bolts anyways so this may be the only issue. than they could be made thicker than stock and will provide some more strength to the head assembly as a whole. Maybe they even have holes for the head bolts, and the head bolts bolt through the guide plate for more rigidity????

just a thought, any comments?

also one other thing, if they were custom made they would then also travel around where you had to grind to make it flat, thereby keeping the aluminum on the head and preserving head strength aswell as giving you more room to hog out the top (if need be).

There is no reason to hog it out up there unless you make a custom intake manifold. There is still metal there to grind, but I already ported that before I ground down to make sure I had enough room. If they were custom made, that would kick ass but the quantity might be high to have them made for a decent cost each. It would probably be cheaper to modify the head.
