Trickflow Valve Covers with 1.6 Rockers

It’s been awhile but yes. I do have a timing tape that shows every 90 degrees

This is a good read on proper procedure. Doug's post#8 pretty much nails it

Checking / Adjusting Valve Lash

Except you're setting preload, vs lash. Best case scenario is to thoroughly read the instructions for that make/ model lifter. And report back

Trickflow Valve Covers​

Maybe it’s just the picture, but those don’t look very tall. If you’re committed to using them, a set of spacers can be added for additional clearance.

I have a 440/505 stroker with Trickflow 240 cylinder heads, hydraulic roller camshaft and Hughes roller rockers. I wanted to keep the stock look so I had to clearance the baffle in the valve covers and use a spacer. Otherwise they would hit.

Some hydraulic roller cams (and some hyd flat tappets too) have aggressive valve timing events, and are kinda noisy as a result. Similar to a solid lifter tick, just a little more subdued.
The noise might be a function of the cam selected.

Probably this.

Those holes are where the adjustment screws are?

Where’d you get the the spacers?

Yes the holes were needed to clear the rocker arm adjustment screws where they were hitting.

Thank you. I will see if I have any spots being hit by the rockers.

I still find it hard to believe rockers hitting the covers is your issue. Doesn't make sense.

it does happen , I had that problem , out of dumbassedness , when I built my 505 , a lot of rocker sets have 2 intake rockers that are diff on the corners for just that reason , they go on the end valves , to clear the corners of the rocker covers ....raised port heads, and 600plus lift roller ...

It's not that it couldn't happen with various combos of parts.. but this is TF heads, with TF specific rockers, and TF valve covers. It works fine for TF, and I know people at the track with the same package that works as it should.

 

[Road Grabber]

Just to clarify. I am not using TR valve covers. They are an older Direct Connection chrome set of covers.

Ahh ok, the title set me on the wrong path..
This one worked fine, but they were comp steel rockers.

 

[Road Grabber]

Any suggestions besides looking at the rockers for markings checking clearances once I get the covers off?

I have a feeling it’s not all of them hitting if at all. It’s not a loud rapping noise. Could be very slight hitting or the hydraulic roller lifters as suggested previously.

re read my post , there could be 2 intake rockers that have 45`d corners ...

Got it thanks

If you see witness marks from the outer rockers maybe try a steel core gasket... those things are pretty thick.

What kind of preload adjustment do you use at the rocker?

What kind of preload adjustment do you use at the rocker?

Expect a typewriter sound with that set up running Harlan Sharps. If you would have used the Mancini 1.6 rockers made by Harland Sharp you would have almost zero noise. They are not there top of the line but most people love them and have quieter valve trains using them, especially complete roller motors and I am running this set up and my engine is way quieter than my buddy’s who used the top of the line HS rockers.

Trick Flow covers shouldn't have an issue with HS rocker arms. Your engine builder should've checked for interference. If he didn't then pull the covers and look for witness marks. 1.60 rocker arms are the same length as 1.50 rocker arms since the pushrod is moved in. The rocker arm is not physically larger since the roller tip has to be centered on the valve. The big problem with the Trick Flow valve covers is that they aren't really designed for street use. They are more of a race valve cover.
