Yes, everything looks like it should be fine...the only thing you may have to worry about is the valve covers with the 1.6 rockers...but lots of people here have done the conversion so someone should be able to chime in on that. And you can always add the Hot Cam, with or without any mods to the heads.

If you have aftermarket heads the springs will fit if they are machined for a 1.43" spring pockets. These springs will not fit stock GM LT1/4 heads without machining the valve spring pockets. The 7/16 studs will not work unless you machine the heads to accept that thread. Stock threads on all production LT1/4 heads are equipped with 3/8-16 threads.

The springs are more than adequate for a HOT cam, but you would have to machine the heads to be able to use them and the screw in studs. So in reality, no the stuff can't just bolt on. They could if you have your heads machined for the parts but that would require R&R of your heads. The springs are superior springs and the rest of the parts are great parts if you can use them.

The studs are a 7/16's upper thread, not lower thread, they should thread into the head fine, but accept a 7/16 rocker.
