we think it is holding the exhaust valves open on cylinder 2 and 4  but we have tried everything to get it right but nothing seems to work the car just runs like a bag of crap

that sounds like someone has lapped the valve seats in too far, Andy had a similar problem once too.

Yep, I had the same problem with a BV head I've got. It could've been fine with a stock cam if it had a smaller base circle than the aftermarket one I'm using.

Have you tried a static compression test with the Eaton cam installed?

my engine will run perfect with the standard g40 cam in but it just wont have this eaton cam at all i had not thought about the valves being lapped in to much could this cause that though ? i mean surely the tiny amount of metal taken off a valve seat would not cause it to be held open??????????

Like I said, I've had that happen to me. Stick the Eaton cam in and then do a compression test.
