incomplete top end set

Comments On Oct 19, 2015:kit contained base & head gasket only. Did not include steel valve cover gasket or exhaust port rings. How do you do a top end without removing the valve cover? Quality is there just didn't get everything to finish the job.
TECH NOTE : WHEN ORDERING GASKET KITS REFER TO THE PRODUCT NOTES FOR KIT CONTENTS.

Good fit, poor item description

Comments On Sep 01, 2015:2006 Suzuki DR-Z400S
Quality and fit look good. Haven't finished building the motor back up yet so I can't speak to performance but I don't anticipate any problems.
Item description and kit contents were inaccurate based on info on Cometic site, and didn't seem to be the fault of Rocky Mtn. To their credit, RM sorted out the issue quickly and to satisfaction. I see that the description of this item has changed here on RM ATV/MC, but not on Cometic's site. Very strange.
The base gasket in this kit is a single layer versus the OE three-layer, so be careful with your compression ratio. Cometic really ought to highlight this since it's a noticeable distinction!
