Supertech vs OEM valves
 

Presently doing a build on a LSJ. Have the TVS supercharger, forged pistons, new forged connecting roda and a brand new cylinder head. Have a comp cams stage 2 cam and Supertech Springs.

I have some used Supertech valves (about 6K miles) or can use some brand new OEM LSJ valves.

Any thoughts on what would be the better combination? Pros/Cons

depends on which supertechs.

If you wish to switch to non OEM valves, you will beed a valve job

Anything else is groovy
