Yup!
closest was the old c4 vette in my avatar, but there i bought a brand new set of edlebrock heads.
The old c4 was also just heads, camshaft, exhaust.

I also used the cast iron heads that came with my vette as a gate stop for a few months.
then finally i tossed them in the garbage can.

And the pan has been "port matched" to the block for oil feedz.
did some overall flowing of all of the oil passage ways in that pan.
more of a general "looks about right" job.
garage door closed, AC on.
Waiting for it to cool down in there, and then i put the pan on!
I have one set of valves installed with the old springs, and another set with the light weight test springs installed.
Pretty much i need the actual springs in place so i can compress the new lifters to confirm pushrod length.
Hoping to get the engine ready to install for next weekend.
the heads go on afterwards, so no real hurry there...

So, ls 7 lifters.
Looks like i got a good .095 - .099 preload with 7.4in push rods.
that's with a .030 headgasket (.040 quench)
I still need to have the heads surfaced, so they might take off another .003
the head gasket i'll end up running with is the .027 (mls)
Reading online, seems the target preload is .080 - .100...
So sounds like i'll be in the ok range, or does it sound like i need a slightly sorter pushrod?

First attempt at replacement of those radiator baffles.
Used sheet aluminum.
used a screw driver to give it some stiffening lines...
I also found i had some nice reusable push lock retainers that fit the holes perfectly!
I'm sure this will make a terrible sound on the freeway, so I'll probably give it some rubber gasket or something along those lines.
