CHeVy Vortec 350 . Timing pointer??

can a standard timing pointer be used on these.. as I've been told the crate engines don't come with any??
or am I doing the oil piece of wire bent around a timing cover bolt and homemade pointer trick
don't have engine here yet to look at it.. to see..
I'm guessing (dangerous) that because the timing cover is the same bolt pattern that any timing pointer for that size balancer should work..
but, not 100% sure..

thanks..
