My KB block came with 7/16 heads studs. Ken was supposed to make it 1/2" and my heads were drilled for 1/2". Can the block be converted to 1/2 and is it really a necessity to do it. Planning on 12-1, 800 HP build with maybe a 200 shot of nitrous when done. BES said they could do it but the guy on the phone didn't sound super confident when he said it.
Thanks in advance.

You don't need 1/2" for your application. It would cost a lot to ship it to a good shop, then again to ship it back. Then it would cost for the work. Then 1/2" studs would be pricy. I would leave it alone.
