First engine build.

The Rhoads take 10-15*'s out of the duration. This amount depends on the pushrod length and how far it depress' the lifter. It must depress the lifter greater than .010 or lifter damage will occur. You'll need a pushrod checker, which you can if you want rent from Hughes engines. They will refund the rental cost if you purchase there pushrods.

In short, yes, mostly.
