I often contemplate the design of the 8V tappet covers which don't allow fitment of the knuckle duster type head protectors often seen on older 2V pushrod engines.
It seems that most 8V tip overs result in tappet cover abrasions or holes, and even some head fin damage.
Crash bars are ugly and as reported on other forums, some suffer from poor fitment and ineffective crash protection.

My theory;
1. Using a damaged cylinder head as a jig, bolt down a tappet cover as per normal to prevent warping.
2. Weld four pre-drilled and tapped lugs around the out edge of the tappet cover.
3. Repaint it.
4. Laser cut or CNC a pair of cylinder head protectors to suit.

Could be done on an exchange basis by any enterprising ghetto member ..............................................

Yes i like the idea of the old head protectors for the 8v, does the picture you have uploaded fit them?

Pic is just an example of the knuckle duster type for a round fin, will not fit the G.

This worked well for the older square fins - of course it was straight when new, but you get the idea - no welding involved, just longer bolts.

I think I read about 6 years ago that the 4 valve heads are put together in a manner that makes this kind of guard dangerous. I recall that there is a good chance of inflicting additional damage beyond the cosmetic. Maybe Pete can clarify or call BS on my claim?

If you're talking about a guard that attaches via the valve cover screws, then yes. You could shear the support pillars right off the cam box. Can you say 'expensive'?

I think the best bet is just to get an extra pair or two of the valve covers.  Cheapest way to go in the long run.  I just picked up a lightly used RH cover for $10!

Minor rash can be polished out and repainted, which is a great opportunity to get funky and try a different color scheme.

Here's a little VHT Cast Iron Metallic for ya... Thumbs Up
