Hello yall. i am going to be purchasing heads very shortly from tsp. I am thinking about picking up a set of harlan sharp rocker arms with them. Is there any issues were the rocker arm hits the valve cover? Do they selll spacers that work well to solve this problem? Any info would be great. Thanks

Mine didn't hit the valve covers but I needed both spacers and shorter pushrods to get the right preload.

What cam were you running, and were the heads milled at all? thanks.

5.3L heads with no milling and TR230 cam. Make a long story short, I did a lot of research on proper installation of these things. Every setup is different so don't go by what other people have. I can tell you that these things should only have 0 to maybe a little over 1/4 turn for the right amount of preload (after finger tight). Anymore than that and my springs would compress.

Not sure about the TSP heads, but these rockers will hit on '98 heads. Tons of post about this.
