You missed the point- entirely.
I don't care what you do or how you do it.......not trying to convince you of anything, other than-
A value needs to be placed on the effort, time, parts........one repair vs another........then judge or discern which solution is best.
And which solution is actually a solution in the long term, most people are shortsighted. Save a dime today and spend a dollar tomorrow.
I just looked it up.
Summit, Felpro head gasket set, 4.0 $110
ARP head bolts, $87
Oil and filter.......no BS here- $40
Coolant- $15
Cleaning supplies and misc sundries- $40
$292.
What is one weekend of time worth?
Now, if that does not solve your problem.....? Chuck a weekend and $300 to the trash and start over again.
In the real world, and I don't mind telling, I earn $200 per day, that is what my time is worth to me.
So, two days and $300..........$700 project.
Now, will I spend $700 and not spend at least the $250 for a valve job? No, I won't, so add that into the equation.
I make general statements for the most part, I don't get personal, it may be your thread but it's not about you.
There are many others who take what someone says as the Gold Standard of knowledge. Providing the balance.
