Adjustable rockers vs non adjustable
Hi
I have a 352 that has the adjustable rockers and my old engine did not. My question is are the actual heads different? I have not looked for the head numbers, but can I take the non adjustable rockers and put on the other heads?
I guess I am just not used too or comfortable with the adjustment on these. I am hearing valve clatter and it seems easier to just have the non adjustable type.
Thanks
Jim

If you're going from one FE to another, to my knowledge it would work just fine. If you are building the motor, you can rid it of valve clatter by going with a hydraulic lifter cam if your block is set up for it.

Non-adjustables vs adjustables. Non-adjustables can be run with a hydraulic cam only. You don't have to adjust them, ever. Rocker ratio is 1.73 to 1. Adjustables you can run with a mechanical cam or a hydraulic cam. You have to adjust with a mechanical cam regularly, with a hydraulic cam usually only once. Rocker ratio 1.76 to 1, which means more valve lift with the same cam over the non-adjustables. Both types will physically fit on all FE heads exceot the SOHC 427 and the Tunnel port 427 heads which I doubt you have either one of.

Cammer heads were the only one's that the rockers are different. Stock adj rockers were used on the Tunnelport, Medium Riser and High Riser. TP and MR use a wider rocker stand than for valve spacing than the LR. HR used a shorter rocker stand but same width as the TP/MR C5 stands.
