I changed the manifold to the matching trick flow max wedge port manifold and used the same carb. I added an adaptor / spacer under the carb.

Has a plan for the repair been decided on yet?

How short of a adapter/spacer were you able to find? I am looking for this solution right now, due to limited clearance... I have a scoop, but not very tall. So I am concerned about my options in this scenario. thanks in advance.

That's a nice pickup. Whats the rest of the engine combo?

I called Trick Flow customer service. I was asked to write an email letter explaining my issue with the heads, the test I've done and to send pictures of the heads, engine and car. Trick flow wanted see and inspect the heads, they sent call tags for the heads. The heads are now in their possession and I am waiting on the verdict. Their customer service has been reasonable and so far helpful.

The spacer I'm using came from AR Engineering, I bought it from Brad H here on Moparts, he was kind enough to sell me his because AR Engineering doesn't make it any more. Its 1/2 inch tall and has a taper to the bores kind of like a shear plate. It seems to work well. My carburetor has a dual pattern base plate.

It's a .030 over , stock stroke 440. 11.7 to 1 cr. 260/264 Hughes engine cam. 1.6 rockers. 2" hooker headers .

Thanks. I know of that spacer, but unfortunately it is not available anymore. I am trying to find something that will be comparable to that setup. Haven’t had any luck yet. Thanks again and good luck with the TF warranty, I hope they do right by you.

I'll sell the design rights and the CAD file to someone who wants to make those low profile spacers.

Yep, I had Andy's last one that I purchased when I was a still interested in an MP RB 4500 intake to test with a 4150 carb. The OP needed one about the same time that I gave up finding an intake that wasn't already hacked on or way overpriced (IMO). Nice part, which what I've come to expect from Andy's products.

Did the top of the pistons show either contact or a pattern in the carbon at the valve? Can you post a picture ?

This is cylinder #1. The one with the most leakage. There is no sign of contact that I can see.

Hmmm, what does that leave as a cause ? Inconsistent or insufficient seat harness ?

Sounds like defective heads to me

Talked with Trick Flow today and spent some time answering questions about my combination in an attempt to figure out what happened to the heads to cause some of the exhaust valves to leak.
Bottom line is my heads are getting fixed and should have them back in a week or two. I'm pleased with their customer service so far it's been easy dealing with them.

Awesome!

That is good to hear Thanks for posting your results.
I'm thinking of buying a set of their 270 soon

Did TF concur that there was an issue with the seat sealing surfaces?

He didn't say, just told me that the heads were being fixed. He did comment that they were were not that bad, but from the line of questions I was asked, such as shift rpm , spark plugs used , total ign timing, type of fuel used, rocker arm used, cam part# and who made it, that there was definitely an issue.

It's highly commendable they are fixing them for you. Most places I don't think would do much to help you once their parts have been installed and used.
