Yes you can still use press in studs but depending on the cam size your taking a gamble if the lift is over .500
You can use a flat tappet cam in a roller block with flat tappet lifters. The roller blocks lifter bores are taller so they'll ride lower in the bores. You would need to use the old flat tappet push rod lenth.
However you cannot mix lifters on cams such as roller tappets on a flat tappet cam and etc.

Yes, you can use the beehives from the LS6 or series 2 v6 engines. They have about 300lbs at .500 lift.

The rumors are true vortec heads are awesome.

I can get part numbers and everything my build used. I tried in a post about a year ago . Then there were some questioned I could not answer, but tried to give as much information as possible. Look in my projects. My cam is the performer and with the matching intake it is a nice street combo.

An E Force supercharger is being added currently. So my attendance is hit or miss here.

Here is a pic of the GMv6 beehives on the vortecs. The small retainer adds some lift but thr seals contact at about .460 if remembering right.

Just remember the beehive type springs use a different retainer than the stock springs and since you are asking about using pressed studs, I'm guessing you aren't using guide plates. If that's the case, you need to use self aligning rocker arms.

Use a timing set made for a flat tappet equipped engine, not a timing set for the hydraulic roller cam.

And as DV said- do not use a roller lifter on a flat tappet cam or vice versa. More here. In fact, you might want to look the whole article over, and there are links to some good info on breaking in cams, etc.

Good luck.
