#05: Phillip Kelsey: "I have seen a dramatic decrease in the spread between hottest and coldest cylinders. The cowling takes less than half the time to R&R versus the old one. I also used 10 pound struts to hold the cowl lids open. I spent well over 120 hours installing it due in part to not devoting full time to the project.

Gary: My only recommendation is not doing the baffle seals with straps and using solid rivets.  It damages the baffles and makes further replacement nearly impossible. Use the large area 'pop' rivets and it will last just as long and take a fraction of the time to replace.
