Lifters losing pressure.

I would just let them pump up. I would use it as a leaning experience. I won’t put a hydr cam in anything. You can make an argument for a stock build, but do you want to build it again because of a crappy lifter? Are you going to spend $800 on tool steel lifters on a stock build? Who makes a high dollar, almost guaranteed to work HYDR lifter? Most high dollar, a tool steel lifter is a solid lifter. The idea of a hydr lifter is ease of Maintenance and ease of production. The maintenance of a solid lifter is overstated. You will need adjustable rockers for a solid, but adjusting it and checking it once a year is like a physical for your motor. You may catch things going south in the beginning. Before they get really expensive.
