You could set-up the gopro in time-lapse mode at a fixed position over your working area and just see how it turns out. Maybe someone here will be willing to edit the footage (not me for sure, I suck at editing).

Edit: Strapping the camera to your chest might work too depending how much you move.

First.... I should have a contest... "How many safety errors do you see?"


Part of why I do photos... is I can edit them... and show what I want to show... and keep my skills/techniques less visible. Another big reason.... doing port work is a passion... doing all the other crap... less so...


sooooooooooo..... back to THIS build......


Crank and rods are ready..... bearings selected





Blocks, appropriate ones for a S/C build(7 rib none drainback, non notched/20V oil pan), are getting tougher to find. It took me nearly a month to find this one! And while the bores were fair, and standard, this block required .008" removed from the deck because the surface was that poor that it required that deep a cut. I'm using a metal gasket, so since I can size the gasket, the deck is cut enough to provide a good seal

THIS is the costliest part of the job..... below is OST-042 in mid surgery. All the original valve seats have now been removed. This requires welding a tool to each seat and then using that welded on tool, to aid in removing the old seat. Once all the old seats are out, the machine work to fit the new seats begins. We see this on the intake side, all new seats, the exhaust side has had the old seats removed, and its waiting for new OS exhaust seats. The intake seats all sit above the deck, once all the seats are in, each one will be machined back to be flush to the chamber. At that point I'll get the head back, I'll do my port work, and once the port work is finished in the bowl areas, the 3 angle will be machined into the new seats.

will you do a flow test on this one?

Thanks for sharing all of your work! Your head work is always amazing!

Where can i find you on FB?

banpei is right.... documenting some tech on video would increase your audience in an instant.

Yesterday i shared a 4AGe disassembly in 2min video i found on Facebook, that boosted up views.

Thank you.... but it only took me 28 years working in, and around the automotive industry to find this niche......




The head is back in my possession, all the seats are now installed, and they have each been machined flush to the chamber


(look @ those exhaust bowls and the massive amount of material removal that will be happening)

on the right you can see the first 4 intake bowls have been roughed out, while intake bowls 5 thru 8 have yet to be touched, AND the exhaust have yet to be touched.


A bit closer view of #2 intake cylinders bowls - before, and after




Note the uncut seats.


And after a weeks worth of work.....




Intake short radius's...




and the intakes from another POV....




The intake bowls/ports are mostly finished..... at least until the seats are cut, and I can get it on the flowbench.

Since I'm assembling this engine with ARP head studs, the oil passage is over-drilled to accommodate the thicker bolts
