A few people in the Pantera circle claim they had problems with rollers. Make contact with the manufacturer about maintains, to make sure you handle the thing right.
I have run a mechanical roller for 5 years with no problem. But I do check rollers and lash frequently every 600 miles. Lash is important since too much may make the roller to float the cam and stop rolling.
351 have no water in the manifold, so checking roller is not to hard. (good idea, just like the Hemi)
A 230 dgr @050 and 110 Lc is about right.
Don�t get too concerned about exact numbers.
They vary a little between manufacturers.
You don�t notice any difference.
