AND, if the pistons have not been re-notched from the Iron Head days ... 8 bent intake valves, also.

the valves aren't bent . I just had the heads gone through 2 weeks ago .  the pistons also didn't show any marking showing that there was any valve clearance issues .the pistons may have been recut but I don't remember them being done

JE like i first stated .  The pistons have been in the motor for probably 15 years or so purchased by my dad .   Everything else is correct tho (correct as in type and brand )

Is it possible that these pistons were fly*cut at some point to clearance a big cam and that is why the valves are not bent, because a mis match at 7200 rpm would bend the valves for sure. I would recommend finding the baseline by removing the heads, checking all the clearances, advance the cam check again, check the pushrods too, then look at the gears, stroker etc. for the winter changes.

Unless your TRW pistons have had other notches re-machined or the camshaft is installed way retarded the valves WILL make contact with those pistons using a camshaft of that size.
Of course if those TRW pistons are for a 460 and .100" down the hole at TDC then there wouldn't be any contact.

I have built HUNDREDS of these, (not embellishing), HUNDREDS and this is how it is.

You don't know what combination you actually have ... that is crystal clear.
So, you don't have to put up with me telling you anything else to try and help you ... at least until you can convey exactly what you do have.

EDIT: I tried to attach a photo showing that the notches for the two heads are 5/8" of an inch in a different place but, i must not be doing it correctly.

this^^^^^you can check clearance @10* before tdc for ex and 10* after tdc for intake with a dial indicator.

I feel like You guys Think im argueing with you About stuff . Im not at all trying to argue im just stating what i know ( and its not much ) . I no the valves dont hit the pistons. And that the Piston isnt .100 in the hole . So they must of been recut . We have had 2 solid rollers in this motor with these heads. First cam was. A comp cams.728 lift .260/.270 @.050 . And was installed by the same guy that built the motor . But it broke a lifter(#5 exhaust). And hurt the cam so we had this new cam ground and put in. Which doesnt tell you shit about the pistons other than. the clearances have been checked at least once by the builder and the heads /valves. Checked. 2 weeks ago when i had him change the valve springs and retainers for the new cam

The first cam was closer but, still to big for that vehicle combination.

The piston being .040 and made by JE is enough to tell me it's a custom piston. That being said , it could have a valve pocket for the Aluminum SCJ head "by accident" if not intentional. There "was" some confusion years ago when "SCJ" was called out for cylinder head type. And it "could" have cleared with a smaller cam and iron passenger head.

Sorry missed the "they're TRWs not JE" post so disregard the above. I also do not know how the valves clear the pistons when using the SCJ aluminum head. The "new" valve location of the head is WAY off what the piston "should" be.

He also said his old cam was a solid Flat tappet, and then it was a Roller, I was at the track a while back and a guy was having troubles with his car so I thought I would help him out, so I ask him where his timing was? ( he pointed to his distributor and said right there) I turned and left
