Well typically if an engine is rebuilt they bore the cylinders 30 over. Mic your cylinders.

If the rockers dont have a number a number stamped on them they are likely stock...go to summit and have a look at the roller rockers to give you an idea

if it is aftermarket, it most likely has a brand or part number on it.

for instance my tfs heads, intake, rockers, and even pushrods had TFS or Trickflow on them.

Click to expand...

Even from the factory they would look honed. When i took my 50,000 mile '85 GT's motor apart the walls had crosshatch up and down the cylinders. I know for a fact noone other than ford had been in the engine.

Look for ford part numbers on various parts and see if you can mic the cylinder wall width

The easiest way to check for un-ported e7's is to feel for the little hump in the exhaust port. You will know the hump when you see it, its along the top.
