small block timing and header bolt questions

[nrt69]

1- how do you set the timing on a small block that has a driver side water pump outlet and a power steering pump in the way of the timing marks?

2- ive got a small coolant leak coming from the first driver side header bolt, any suggestions on how to fix? ive tightened it as much as possible.

I used Permatex thread sealant with teflon on my header bolts. Worked good. I would dry out the threads in the block good before installing them.

You have mismatch of parts.
There's two ways to fix it.

Put a 1970 or newer style water pump on the engine and have a radiator shop modify the lower radiator tank.

Put a 1969 or older timing chain cover on the engine and with a piece of timing tape on the harmonic balancer move the timing marks.
