I'm not going to go into why or why not-----
But, I do have to comment on a few things---
If you are going to change the heads, do it in the car--just be careful with the fenders--You are more likely to damage the car pulling the engine than working on it in the car---
Just keep in mind that as you go along, you may get to a point with what you find that will result in you removing the engine---
As to the use of dial bore guages and torque plates ----doesn't happen in this case--you are removing pistons and reinstalling in the same holes--sizes won't be an issue
The use of a flex hone doesn't require a tirque plate---they are flexable and do not change the straightness or crookedness or out of round of a cylinder and THAT is there biggest selling point and reason for using them---
If you are removing the
oil pan to fix a leak, you should check the bearings for wear patterns, this will require removing the
oil pump and you can change pump or drive while doing that--you might want to use High PRESSURE pump for the added plumbing of an remote filter---
ERA Chas---If I had any engine with 10% leak down it would come apart---I'm sure you must mean 2 %
