CJ Heads: some valve bearing trouble
Hi people!
well, I was prepairing for some portmatching on the heads and intake, when I found this...
(look at pics)
what you're looking at is a broken/cracked casting where the valvebearings of the intakevalves sit.
anybody got some ideas about this?
do i have a problem here?
I bought the heads when they were already rebuild and maged and hottanked, so it would be a setback if they are a write-off or need a new rebuildingjob!
any thought is welcome, thanx,

some body put a new guide in and broke some out. as long is that guide is good press it will be fine i have weld them up but would not do it if they are done this can happen if the valve gets bent and break is part of the head or a hot head with a guide driver

Yep as Pat said they should be fine. It's fairly common to see on FE heads when the guides are replaced. I've had the guides replaced on a few sets of heads and a few of the guide bosses chipped as yours in the pics. G.

pfieeeuw!! was a little worried there!
But I probably will have to check if there aren't any other chips coming of, or are about to ... better now than when the engine is running, right?Going sideways through a bend isn't considered normal or even sane, so that's the way I like it!

Right and another concern would also be there is no further cracking involved also. In most cases that I've had it was just a chip and no further issues. Are those C8OE-N heads???

yes that's right a c8oe-6090-n casting, why do you ask?
and by the way... how are you able to see, from just a pic of the intakevalve-chamber, what head it is???
...and spot on with the casting number...
I mean, I know I'm just another newbie in this FE-engine stuff, but this is
incredible... ( but hey, I'm quite easily astonished
)
