Here are some factors to consider when deciding whether or not to resurface the block or head:
* The condition of the surfaces. If the surfaces are flat and free of any damage, then you may not need to resurface them. However, if there are any irregularities or damage, then it is best to have them resurfaced.
* The type of gasket you are using. Some gaskets require a perfectly flat surface, while others can tolerate some minor imperfections. If you are using a gasket that requires a perfectly flat surface, then it is best to have the block and head resurfaced.
* Your budget. Resurfacing the block and head can be a costly process, so you need to decide if it is worth the investment. If you are on a tight budget, then you may want to skip resurfacing the block and head and just replace the gasket.
Ultimately, the decision of whether or not to resurface the block or head is up to you. However, by considering the factors listed above, you can make an informed decision that will help ensure the success of your project.
