Roller Rockers on LT-1

John Nechiporchik · 11-20-2014, 05:26 PM

Going to install Roller Rockers on the LT-1. Also, planning on going to head studs since I have the motor apart. Somewhere I read/heard that there are potentially interference issues when using roller rockers with studs.
Any input/wisdom/solutions on this issue....if one exists.

Thanks,
John

Shouldn't have any clearance problems with the rockers to head studs, I would recommend the 12 point nuts. If you are going to hone the block (recommended), make sure you do it with the studs installed first. Using the studs with torque plates to hone the block.

You'll want the 12 point nuts in the centre 4 locations between the springs for wrench clearance. I also ground a couple of threads off of the studs in those locations so they didn't scrap .---Trevor

I found it necessary to use adjustable guide plates to maintain proper alignment.

You might want to rethink head studs on an LT-1 stocker if ever go to tear down, a little tight getting the heads off in car.

Just be sure to check your cam lift with roller rockers. Just because they say 1.5 doesn't mean they really are. Comp cams stainless steel rocker arms are some of the truest to size.
