They came in quick and are quality products definitely going to be using michigan motorsports for performance parts.
I bought this kit so i could do a maintenance valve spring swap on my current cam setup because I have a little over 30k miles on my cam and valve train component's. The quality of the kit was great and my valve train sounds nice and quite. I ordered the kit late Thursday night and it was shipped out Friday morning and arrived on monday afternoon. Overall great product and Michigan Motorsports ships fast.
