Flexplate bolts. I searched it and found people are having problems with Arp ones. The head on them is too big and does not fit a socket well???

Yes, that is correct. The large 12-point heads on the ARP flex-plate bolts do not allow space for the socket between the crank hub lip. Get a new set of OEM (GM) flex-plate bolts. Also, use a thread locker and make sure the flex-plate isn't powder-coated.

ARP came out with new ones that have smaller heads.

You realize that this is not an LT1 specific piece but is generic? If you have stock rotating assy., you can buy a flexplate that is a simple bolt on as it is already balanced against a stock bob weight. If it's for the combo in your sig, which looks like a non-stock setup, it is going to need to be final balanced. You probably already know this, just pointing it out to those reading who think the piece would be a simple bolt-on.

Rich, whenever you have something to say I am all ears. Over the years you have tought me alot about these cars. My motor has a stock crank, with forged Speed Pro pistons. I need the flexplate for the Machine shop. This weekend they are going to get everthing I have to assemble the long block. :D oooh happy day!!!!!!

Great feeling!

A "generic" flywheel like that will usually have a large balance weight. The machine shop will balance it against your specific assembly by drilling shallow holes in the weight to remove the necessary amount.
