What's the part no. for the Manleys? I did not know they had
an LT1 guide plate.

 

just out of curiosity, does anyone have a pic or two comparing the sbc or combination motorsport guideplates with the correct gm or aftermarket ones? I'm curious to see the difference.. I found a pic on shoebox's website showing the resultant rocker orientation:

but was interested in actual geometry comparisons..

 

I adjusted the Iskys to get the rollers centered front to back on the valvetips then tighten the stud, at which point the plate moves and you start over again, is a PITA with everything oily and yes I think it would be a big headache in an f-body. I can actually get to my engine and it was not the most enjoyable project.

 

...much easier with the engine out of the car they are the only way to go, IMO.

 

Wow I haven't seen you around much... how's things over on LS2?

 

Isky's werent that hard for me to do, and it was my first time

GM bow-tie plates here, but I hardened them my self since GM dropped the ball and did not do it. They work perfectly.

 

That is why I specified in the car. On a stand on a dry head I bet it goes much easier.

The GMPP plates DO NOT result in perfect alignment, only "good enough", I tried Comp before them and that alignment was BAD some valvetips were not covered.
