Can anyone say for sure if these will bolt directly onto a 5.3 liter engine? Thank you for your help. I tried searching some and didnt find anything definitive, so new thread.

LS1 LS2 LS6 Stainless Steel Roller Rocker Arms Adjustable w Hardware Chevy 1 8 | eBay

 

I can't speak for the quality of the product, but yes. That is the correct application according to the seller's listing.

 

What are you thinking the reason they wont work???

 

This... But I would be scared to run them.

 

I run comp roller rockers. If I had to do it overagain I would have just used the stock rockers with the trunion upgrade. I actually almost switched back when I did my latest engine. I bought the trunion upgrade, and installed them in the rockers. I changed my mind at the last minute just because I had them.

 

I just wasnt sure if the rocker system on ls1 heads are the same as what comes on the 5.3 heads. Any reason why they may not be trust worthy?

 

Yes it will.

 

any updates on this rocker..

 

I ran the Ebay sold pro comp non adjustable aluminum rockers in a 1.8 ratio and stock valve covers and I had to clearance the VC in a number of places to keep them from hitting. Those have adjuster screws that are significantly taller than the aluminum bodied rockers I got. I think you will need taller valve covers.

 

Ahh thanks for that info. Spacers or new covers def add to the complexity some and the expense. I think I will just wait
