Cam plate question?

I've found them all ways, hole, no hole, no plate and a hole..
I like to run the bolt with the hole and a plate or make one with a drill.
Make sure to use a good timing set. Dont use the edelbrock cast gear crap set for cheap.99 ..get a 90-120 set billet gears and good Japanese or USA chain. Just skip the china/Taiwan chain sets and cast gears that have the s402 on the cam gear.
