Your site mentions "you will need dual springs to run these cams", I'm assuming GSC beehives will work fine though?
Should installers be carfeful to check piston to valve clearance w/ these?
Just trying to get some answers before I change out my GSC S2's.

These are very aggressive so I recommend the Duals. What pistons are you running? Yes, You should check clearance. I would imagine they will work with anything aftermarket though as we have not had an issue yet. Most if not all aftermarket pistons have a larger valve relief area than stock.

No they will not come with a cam card. No specs will be provided.
On both cars we tested them on they worked very well straight up and did not need to be degreed.
As far as the pistons they will work with without hitting goes, The only thing we have tried for sure is Buschurs 10:1 pistons. They do have a pretty big valve relief though. If you purchase these cams I would suggest checking clearances upon install.
Sorry, We will not be making these for Evo 9's
