Hello everyone,I am doing a Solid lifter conversion on my RB25
here is what i bought so far:
Tomei 270 cams with 10.25mm lift
supertech valve springs, seats and retainers
Tomei Solid lifters
Tomei Cam cap studs


i thought i pretty much got everything until i saw these for sale:

Now my question is.. Are those necessary? because i haven't seen anything on forums at all about those. i searched a lot and couldnt find anything but for sale links..
