It was nice to chat with you Byron. I did order 2 AIRTEX AW9009 water pumps. So I will let the group know if it comes with a cast impeller.
Out of fear of cam/ rocker destruction and what seems an unnecessary expense I will try to source stock nos l20b valve springs or just test and find a matched set of used. I've never had a .180 pad fall out and the AUS pads have the dimple that should help the pad sit deeper, so the thicker retainers don't seem needed. I have a few coffee cans of rockers and springs. I'm building drivers not race engines. Just a cam for the lump at a red ight.
What are the thoughts on reusing head bolts. I have plenty of the upgraded stock ones. With the circle on the heads around the Allen key. Cleaned up they always worked in the past. I did snap one off removing the last head. I hope there is enough exposed to help with removal.

Not sure if it is worth mentioning, or most may know, you can shim the pump pressure up.

I have the higher volume oil pump of course and as my engine set-up basically has a major "leak, what with turbo and spray bar, as the pump came, it could not produce the pressure reguired.

So, we just snuck up with shims behind the blow-off spring, up to the good pressure needed for me. Never touched it since.

Mike,
Regarding head bolts - to me they are all getting old - think that every time the motor heats up, that bolt is cycled one more stretch...
I’ve been using the ARP head bolts (and rod bolts) for years now on my builds.
To be honest - I like the studs & nuts much better from a technical point of view - in regards to torquing.
To me it also seams easier on the block as well. Our old blocks are starting to crack into the water jackets from the head bolt holes as the blocks age - again thermal cycling taking effect. So taking that twisting motion out of the torquing of the bolt...it goes over better for me.

Byron.

Just wanted to update on a few parts I've ordered and received from rockauto.
The Hitachi oil pump for a 1983 Turbo automatic 280zx is correct. An aluminum body and from Japan. Measured the rotor and it's 40mm , so a high volume. The Melling 111 is cast steel bodied, but also high volume.
And the cloyes timing chain kit is now made in China. Don't know how this effects quality. The chain dowels are solid not hollow like some cheaper chains ive seen.
I don't know where to source a made in Japan chain. My machine shop sourced 2 made in Taiwan chain kits. Double the cost. Hard to judge if it's worth the extra.
Felpro gaskets are all made in USA. They are pretty inexpensive so I worry about quality a bit. But the next 2 , 2.3lz builds are getting $20 head gaskets.

Matt Armstrong in Mission is building a fixture on his restored Valve Grinding machine to regrind Nissan Rocker Arms. Then we can get them done locally.
