I have the Trick Flow Heads in my car and never got used to the solid rocker chatter. I am thinking of changing to AFR heads to eliminate that chatter.......Is that crazy?

 

Yes it is. It wont help the noise.
After all you've been through, maybe it's time to buy an 08 and start over.

 

Why not consider ETP heads?

Besides a steering pump problem...........I am satisfied with how she runs now. AFR heads do not need solid rockers therefore no chatter. The chatter is normal for Trick Flows.(Harland Solid Rockers)..thought you should know for future reference I am just not into the chatter and may consider changing the heads.
When I was in Florida I rented an 08 and after driving it for the week I am very happy on how much faster my car runs. It was the first time I had driven another vette.

 

You can't go wrong with either.
The trickflows have been performance monsters as of late.

 

ETP's are best

 

You may want to contact TJWong. He stated that depending on your cam, he has found you need different length pushrods to avoid the additional clatter.

 

I've recently spoke with Harland sharp about the Trick Flow heads. They mentioned coming out with a Trick FLow specific rocker setup. What is the part number on the set you have? Porsche engines have quite a bit of valve noise, I think it means you're fast buddy. Or like some others have said, have it looked at to be sure it's normal. Mine don't really make noise.

Its not loud like I am low on oil its just a chatter that I never really got used to.
I like to think I am pretty fast could use some more low end but its is what it is........
The heads are the TF 225 I do not know the part # on the rockers. I have a small cam 224 228

 

Yes, thats crazy.
My heads/valvetrain are quieter than with the stock rockers

 

trick flow heads?

 

Yes. Set up the valvetrain right with a good roller rocker and it will be quieter. All aftermarket heads should have good roller rockers but trickflow just happens to say that it's required to prevent damage to the heads over time.

 

what rockers you guys using....probably going to go with yella terra ultra lights for mine when i order

 

Thats what I used and they are quiet! Good pricing and service from Byunspeed forum sponsor!

 

I would love to have either one of these heads

 

Their has been a multitude of posts regarding the sewing machine noise. I've not installed my stuff yet & I do not want the sewing machine sound. Somewhat of a agreement on Cadillac Racing Lifters & YT Ultralites combined with correct push rod lengths minimizes the noise. I did choose AFR heads.

 

Here is the You tube of Lingenfelter ported heads with the GT11 cam. It has a little more noise but not much.

Hi par34n5,

Between those two my choice went to ETP 215...
Why???
Because I took a look at the reality of the technical aspect and the best of both brands is on the ETP Heads.

- Valve angle is rolled to 11° on the ETP vs.13.5° on the TFS and 15° for the AFR.
The ETP is the only one who made a casting with the same characteristics than the C5R, GM can't be wrong with the 24 hours Le Mans winning C5, don't you think?

- On the ETP heads the valve-train geometry is PERFECT with the OEM rockers and valve the train deflection is non-existant...
I rev my engine to 7450RPM with zero valve float.

- The ETP deck is the thickest when you compare the two others vs. the ETP...

- The ETP heads are the only one to have INSERTS from the factory to "on the top of the thick deck" improve rigidity, very well engineered sirs!!!

- ETP Factory or any of their dealers can deliver you from the factory the exact volume chamber you or your engine builder wants...for the same price!!!

- On the ETP heads the Intake port volume starts at 215cc then 225cc then 235cc then 245cc...thanks for the choice.

- The price is similar to the AFR and less than TSF when you add to those the roller rockers.

- At the end those ETP 215 in my daily driver stock cube stock shortblock on pump gaz that is so drivable than my wife use it...is producing 511rwhp and 455rwtq... and cruise 1200rpm in six gear or 20mph in a school zone in third...enough say I guess.
Regarding racing, in the big dog world, ETP is used by the best, but if you are racing, you know that you never tell the others what makes you the fastest...no???

The only problem is that ETP is selling so much that they don't need to advertise and you may wait a little more to obtain them vs.the competition.

Wow! Great write up on the ETP heads! Thank you!
