No problems at all. The rear most coil bolts on the driver side are in a tight spot. But otherwise simple and no issues. Let us know how it goes. Post some pics too.

Answering my own question. I confirmed the PCV vents on the LSA factory valve covers are wide open with no restrictors. Hopefully this tidbit helps someone in the future.

As noted by SiC ZL1, with the reminder of the PCV system in a factory LSA configuration the Holleys should work fine.

Hope the install went well.

I installed these a couple weeks back. I just cut the pcv and attached a hose like the previous picture. Worked pretty easily.

Do yours still have the hose fittings? Hard to tell in those pics.. I'm looking to add a LSA or Heartbeat and was wondering since mine are similar to yours except in chrome.

I used a new hose and 90 elbows and then a T at the PVC can on the air cleaner elbow, I did have to cut the hard plastic pipe right before the PVC.
