stock cylinders ported for 4mm

[Machwon]

I have a pair of stock cylinders cut for a 4mm. Comes with race cut stock head and a new pair of 795's at 64.5mm. These cylinders were sent for a drag port to me, the original porting was rather extensive on the intake side. I straightened them out and put a decent drag port on them. The intake sleeve area is very thin, they will survive, just don't drop them. The person who sent these to me has never paid for the work, so their loss. I'm asking $465 shipped.
