Blaster Am I ported?

[jri93]

I recently bought a blaster and believe it has had some engine work done because it has 185 psi of compression with a stock head. So im guessing it has been milled. Also it has somebody's name written on the side of the block. So now im wondering if it has been ported. can anybody tell if it has been ported by looking at these pictures? BTW its a 61x

Cant wait to see how this thing performs now with rebuilt carb and new reeds.

The exhaust port shape and size are not stock.

Main and auxiliary transfers. The port directly across from the exhaust ports is the boost port.
