I think Gary is just trying to be “helpful”, as repayment for me bringing all these iron heads over to his house for flow bench testingPackardV8 wrote: ↑Wed Nov 06, 2019 12:00 pmGoing to have to agree to disagree on this one. We hate doing intake manifolds on the surfacer, so nothing would make us happier than folks fixing them at home, if a fix were generally the result of their effort. However, we've had to try to save so many blocks, heads, intake and exhaust manifolds after someone has been at them with a belt sander, disc sander, Scotchbrite sander, et al. After set-up and machining, we were finding some unsalvageable and the customer didn't feel he should have to pay for the effort. Now, if we see the tell-tales, if we are forced to take it on, pay for machine time in advance. That alone has saved some grief and sends them searching for another piece which hasn't been molested.

Re: Warped intake manifold
To get it to take a set it has to bend beyond where you want it to end up, with gaskets on both sides you can't tweak it in the opposite direction enough for it to end up flat after it springs back.
What about a shim under opposite corners of the end rails, and no gaskets? Tighten bolts at the corners opposite the shims while measuring the gap to the head surface? Tighten bolts, loosen bolts and check to see if/how much it moved.

Hang it upside down on the stand and build a fire under it.travis wrote: ↑Wed Nov 06, 2019 4:03 pmI tried that...set it up on another engine and left it bolted together for several weeks. When I removed the bolts, the gaps came right back. I suspect that idea could work if you could heat everything up a bit. Unfortunately I think a 351w with heads exceeds the load rating on my oven...plus trying to explain that to the wifeturbo camino wrote: ↑Wed Nov 06, 2019 1:22 pm Can you try re-warping it back to straight? Bolt it down to one head, with gasket, use strategically placed bolts and shims at the other head to twist it around and see if it'll take a set where you want it. Leaving the one side without gasket will make it easy to see where/how much it's out of alignment.
