is the use for guideplates only for non factory roller engines?reason i ask is i don't have guideplates on my 87 350 sbc roller motor.when i'am looking at pushrods i see (hardened for guideplate use).i'am getting ready to have new cam installed and just trying to get everything i need or replaced. thanks.

I think it all depends on the rockers you are using. If the tip of the rocker will center itself, you wouldn't need guideplates. The guideplates keep the pushrod from driving the rocker off of the valve.

i do have self-aligning roller rockers.

Then you should be good.

do i need lifter guides and a lifter retainer? i don't see any reference for this stuff just asking if i need it.trying to get all needed parts before installation.

Depends on what you are doing. If you are installing OEM roller components in your block (assuming it is set up for it), then you would install a sheetmetal "spider" that presses on the guides that keep the lifters in. If you are installing a retro-roller camshaft and lifters, you just install the lifters and they have a bar that connects them together.

yes,this is a factory roller the spider plate should allready be there is that correct?

Pre-Tuner 02-27-2010 08:27 PM

Yup, it should all be in there.
