Worked perfect

It fit my BIKE perfect. It now has great compression and no longer smokes. The gaskets were a little scratched but I put some gasket maker in the scratched spots and it sealed fine.

Great parts for the price

Received fast and packaged well each part was individually boxed or wrapped and then all put in another box so that was nice nothing banging around and getting damaged by other parts. Super easy to install headed installed in less than an hour. Honestly can't beat it for the cost
