Overall Assessment

Customers recognize the Ansen 120-4002 Small Block Ford Valve Cover Spacers as a high-quality product, vital for providing clearance for various rocker setups. They appreciate its excellent fit, which aids in keeping their engines' modifications discrete. These sturdy, well-made spacers are excellent for users who prefer running vintage valve covers as they facilitate rocker clearance. The plain finish is nice and straight, sealing nicely, and can also be polished to match the engine. Some customers, however, voiced a need for extended bolts for installation. Despite this, customers overwhelmingly recommend these spacers for their functionality, quality, and price.

Hard to find

These spacers were my only option for retaining my stock cast aluminum " POWERED BY FORD" valve covers. I tried thick gaskets but there was still clearance issues with my roller rockers. The look of these spacers isn't noticable once installed, but they will give you plenty of clearance. The only place I know that carries these is Speedway, which has great customer service and shipping! If you need added clearance these will give plenty of it, even with a stud girdle.

Perfect fit and they allowed me to run my original '66 289 valve covers on a modern 351w with factory rockers. Under the hood of a '63 Galaxie most people think it is an original 289.

I bought these so I could use a pair of swap meet finned valve covers over roller rockers. They do the job of clearing the rockers, but I haven't had the engine running, so I can't attest to wether it seals good. I modified mine on a belt sander by getting rid of the mounting flange for a smoother look.

Hi, like the look of these - and they will be perfect for my stock looking engine. But do you have the correct length of studs available in store?
