GTSIO 520/550 vs reg 520 cylinders for GPU Conversion (COST?)

Postby luv2airboatnhunt » Tue Feb 27, 2018 8:55 pm

Hey folks, I know this is a "running dry" topic, because I've read everything I could find in SA Forum back to 2010 that relates to GTSIO 520 conversion. These forums are loaded with experience (and BS, as, so I found most of the answers I was looking for, but this one....
Looks like the GTSIO cyl, parts, and rocker assy are getting costly. What is the going (avg) price for 6 cylinders, rocker assy, vavle covers, ready for pistons? Has anyone bought any lately?
Now, what about GTSIO 550's? Newer style cyl, are they worth the $? Anyone running a set?

All responses are appreciated,
