New guy here, getting back to an old resto project that's been sitting for way too long...

After I get my 1990 LX 5.0 running again, I want to ultimately install Edelbrock 60329 Performer heads. I bought them 15 or more years ago, and they, along with the car, have sat for lack of time.

Got some time available now, but today I read for the first time that these heads are for flat tappet lifters/cam only--the valve springs are NOT suited for roller lifters/cams....hmmmm. Other parts I have and want to use are Scorpion 1.7 roller rockers, Performer upper and lower intake, suitably sized throttle body, MAF, and 24 lb. injectors--all acquired years ago. Bottom end is stock.

I will be keeping the stock roller cam for the near future, with maybe an E303 cam later if the car still runs well enough to merit it. I will not be going with a flat tappet cam.

Can anyone chime in about the valve springs in the 60329 heads? Can they be swapped for springs suitable for roller lifters? With...? Any insight appreciated.

These are the install notes. Says the springs are good?

Compare the spring pressures installed on the heads to the recommended spring pressures for the cam you're gonna use.
