Default Boosted LS3---valve seal issues

Hey guys I need some help..... I've got a Paxton 2200sl/cam and full bolt ons and 815rwhp on 93oct. gas.....I have needed to replace 3 valve seals within 800 miles of build....now it seems I need to replace more if not the same (car goes to shop tomorrow)

Is it normal? Is their a solution to keep it from happening?

Any recommendations would help. Thanks!

I hope my tech didn't....I switched techs so hopefully the new guy will find the problem and check the seals. Thanks for the help.

I run a 2200 S/L on a built engine by ECS. I am at 867 RWHP I have not had any problems with my valve seals. Hope you get it sorted out.

What seals are you running? Stock or aftermarket?

Others in your engine always means problems. Their attention to detail which is paramount just does not exist. They always mess something up. I hope this isn't the case with yours.

By the way, did they upgrade your springs, retainers and seals? They didn't leave the stock stuff did they? I would think with a blower and cam that the lift etc. would warrant the upgrade...??
