TECH TIP:
Used blocks are better for built motors because the metals have been heat cycled and any distortions from heat have already occured. These thousandths of an inch changes can affect a high performance build.

Valvetrain

Valve Seals Kit

16 new viton rubber valve seals
These come in our spring/retainer kits already, you only need this if you are needing replacement seals.
Single/Stock fits factory valvetrain and single spring upgrades
Dual fits dual spring upgrades and require bronze

TECH TIP:
If you are building an engine (short block), and do not plan on building the head, get this at the very least to refresh your valve seals so they will be new like the rest of your engine. If you skip on this your valve seals may leak in the future. This is a cheap insurance so you won't have to do this later and rip the cylinder head off again.
