Drago's Bike Works farms all their work out
Drago's Bike Works farms out all their work to Zippers or Revolution Performance. Don't belive me email them yourself with the #'s off your heads, or the serial #'s off your cases. You can find the #'s stamped in heads he posts pics that he claims his shop has done. If you visit his shop he has no machines, lathes, bridge ports, boring machine, head machine, if you ask him he will tell you its across town.
I have a set of 110 heads that are off my 117" superchgarged motor, the heads were taken to Drago's Bike Works for port work and what ever he does. They were never touched by anyone else, no previous work done to them.
I found a stamp in the bottom of the heads near the Ex port. I emailed Zippers and this was the response I got.
"Jim,
Hello. This is Pete and we have talked before.
The heads that you have appear to be a set of SE 110 heads. They were originally built as our Stage III Heads and set up for an S&S 625 Cam, 117” engine, and had .005” decked off of them.
Now, these heads were done in early 2017, so I cannot speak to the condition they are in now!
If you need anything for these heads, please let me know.
Thanks!"
