TC Valve Seals

[Velocity1]

Can anybody give a recommendation on which valve seals I should use to replace the stock ones on my '02 heads now?  I'm running the HQ 033, (.600 lift), with Beehive springs so lower profile may or may not be necessary.  I'd appreciate the expert advice available on this issue.  I know the stock seals are metal banded, offer excellent retention on the guides but only have one seal lip as opposed to others with the springs and dual lips.

Thanks.

I know my porter used "Viton" seals for the 37 build I'm running now, on stock guides cut for spring clearance but kept the same guide OD / seal ID, as stock.  Manley makes a stock replacement as does Kibblewite(?) 

Any recommendations on the tried and reliable would be appreciated.   

Thanks.  V1
