You don't have any buddies to call over have a bbq and work on a simple yota head?
First of all the head on a 20/22 is NOT “a simple yota head”!
The early Toyota head is arguably THE most discussed part of any early Toyota vehicle.
If you want a head job on an early Toyota to go 100,000 miles it better be done RIGHT - starting with the machine work, to part selection, and then to the installation.
I have to laugh…. “buddies to call over have a bbq and work..”
With my buddies it would be look at the engine, drink a Bud, grill, drink a Bud, eat, drink a Bud, discuss work, drink a Bud, look at the engine, drink a Bud, discuss work, debate how to do a head job, drink a Bud… Oops… time to go home.
