i like to know if er rocker will work ok on a 3800 supercharge PA

i have heard about instaling then backword the ex on the in and the in on the ex

ZZP actually recommends not to use ER rockers in L67 plaforms, but to use 1.9 modifed rockers. ZZPerformance - 1.9 Ratio Modified Rockers #ZZ-19MR

yeah but i have the the ER and the supercharge engine i will try it thank you

So you came here asking for advice and your going against the manufacturer and what were saying?

They'll be back once they destroy something, you did all you could do Mike, which was give them solid advice based on the manufactures recommendations for the rockers.

tell me how can i destroy something whit er rocker

I can't because I am not the manufacture, I do know they do not recommend using it for your application, so I'd say there has to be some reasoning behind that.
Not really so sure why you came here to ask for advice, when you clearly had already planned to use the rockers no matter what answer you received.

Good luck with the rockers, hopefully they do not have any issues, just know if they do the manufacture is not responsible.

Why would you use something that EVEN the manufacturer doesn't recommend you use on your engine?

because i have them laying around and er rocker are stock rocker juste like the 1,9 so i dont see why they would harm my engine

er are something like 1,8 and 1,85 so not that far off the 1,9 and for sure better than the stock 1,6

Well I can understand wanting to use them since you already have them, I think some others have used them, and not had issues, but I'd see if you about getting it tuned when you are done, you'll probably see 10-15 more HP, as long as you have upgraded your intake and exhaust.

Are you upgrading your valvesprings, also maybe the valve locks, and retainers?

Once I wanted to upgrade mine, but ran out of money to put into the car, I wanted these, along with some Yella Terra'*..
