94 cobra head valvetrain?

How good are the springs compared to the '92 stock e7's? When I install the gt-40's, should I install new springs or not?

I have old post about getting 'valve float' with my g-40's, but i run the e-cam with 1.7 rr's which must have put a load on everything..... i put on some 'comp cams' springs and it pulled much harder, i suggest you do it while they are off, i did mine when they were on, and it was a pita....

I don't know what kind of problems others have had, but I run the GT-40's, B-cam, and 1.72 rr and haven't had any problems.
