Cometic Top End Gasket Set
Titus in AZ
Way better than I thought
Doing a rebuild on my entire motor needed just a head gasket so got this thinking I should replace all my seals for the price I wasn't expecting everything to be this amazing all the rubber seated perfectly definitely worth the money.

Wiseco Piston Kit
Jack in ID
Great pistons
I love wiseco pistons. They always fit well, they look great (which feel reassuring when doing the top end rebuild). I will always buy wiseco pistons.
