Good point, tcasey. Sometimes you have to adjust the rocker arms to minimize noise. Don’t forget to check your lash settings too!
Has anyone had trouble with fitting roller rockers on aftermarket heads? I’m considering a setup, but heard it’s tricky! Any tips?
I’ve had my share of issues! The geometry can differ greatly, so always check for compatibility. You might need custom pushrods to make it work.
What torque specs are everyone using? I know it’s generally around 20-25 lb-ft, but the exact spec can be different based on the manufacturer.

It can definitely vary! For my setup with XYZ brand, I’ve tweaked it to 28 lb-ft. Just a bit tighter for that extra performance!
Remember not to overtighten! Common pitfall I see is folks cranking down too hard, which can lead to rocker arm failure. Take it slow and check adjustments periodically.

So true! I had a friend who did that and ended up cracking a head! A costly mistake. Be patient!
What’s everyone’s experience with roller rockers versus standard rockers? Is the performance boost really worth the investment?
Definitely! The increased efficiency and reduced friction make a noticeable difference. I’d say it’s worth every penny if you want more power!

Just don’t cheap out on the quality! I learned that lesson the hard way – bought a budget set and they wore out way too quickly in my last build. Stick to reputable brands.
Yikes! Budget parts can be tempting, but there’s a reason they’re cheap. Invest in quality and you won’t regret it!
Adjusting the valve lash after installing roller rockers is crucial for optimal performance. It allows for better airflow, increases RPM potential, and prevents valve damage.

Absolutely! A proper adjustment means your engine runs smoothly and efficiently. Don’t skip this step!
I’ve always been told to check lash when the engine is at TDC on the compression stroke. Anyone have tips on how to make that easier?

Great point! I like to use a remote starter switch; it helps with finding that spot precisely.
Setting the lash too tight can lead to valve float, while too loose can cause ticking noises. Remember, there’s a balance to hit!

Exactly! Using a feeler gauge is key to checking and setting lash accurately.
Does anyone else find it fun to see how adjusting lash affects engine sounds? It’s like tuning a musical instrument.

I’ve read that the ideal clearance varies by engine type. What do you recommend for a small block Chevy?
