Default Opinion of RamAir Manifold condition

Removed these from engine to repair exhaust leak from center ports on pass side.... doing engine detail also....

Buddy brought them to his machine shop and trued them up..... I believe he said he took 15 thousands off of them and didnt want to go further.... He said they will seal up fine.

Brought them into my shop( heavy truck shop I manage) and only 1 guy said he would run them....

My friend who is actually helping me with the work doesnt feel that they will seal...

they are 15 year old AMES repro's ..... If I have to replace them..... I will go with the RARE manifolds already Ceramic Coated....

Thanks for your opinions

I have used Remflex. Don't think there will be a problem.

Is it OK to run a "thick" style gasket with Exh Manifolds? I know mine have a small leak, but I run OE style metal stamped gaskets. I am afraid of cracking a manifold, maybe by unevenly torquing the manifold down? Round Port Long Branch manifolds are hard to come by.

I'd check the head surface for erosion while the manifold is off.
