There are way too many variables to say with certainty what will work and what won’t.
This should have been sorted out at assembly, not after it’s in the car. If it is a case of pushrod length.
That’s why I cringe when guys think you can slam a engine together and not check everything. It’s a giant ***** to sort this stuff out and fix it after it’s in the car.
And it’s cost ineffective. You have to check everything. It takes many, many hours to correctly measure and assemble and engine. It may go together 4, 5, 6 times. I’ve done engines that I had pre-assembled 12 or 15 times. On final assembly it went together and went on the dyno without an issue.
