So I forgot to measure the space between the rockers on my big block heads and Im wanting to order up the spacers from mancini this morning. Stock 906 heads, harlan sharp roller rockers. Im more concerned about the large gap measurement.

Mancini shows a few different options, or is the spring the way to go with a hydraulic roller camshaft?

Thanks

Don't use springs , If no one comes up wit hthe number I can measure the sharps I have at home and tell you exactly what they are .

Thanks John.

I didnt think the springs were a good idea with a roller. I have the engine together at my home shop, I just pulled a moron move and didnt measure the spaces. I have a small lathe, so I can cut some down if I get the really thick ones, but Id really like to get this damn thing outa my shop before the weekend....

Thanks again!!

On factory heads the space changes but I use the .030 shims to correct any gaps/center on the valve stem tip.
Edit: if you are looking for the big spacer size I can measure it for you.it is .700!I have my rockers on the kitchen table if you need more measurements.

perfect!!

thats exactly what im after!!

Thanks a bunch
