Checking Pushrod Length with new Lifters...
OK, maybe I'm thinking too hard about this engine build, but I want to get it right. I've built a 388 short block, and I'm ready to put the new AFR 195 heads on. I'd like to check for the correct pushrod length and valve train geometry, but obviously my new hydraulic lifters are flat, having never run in the engine. I doubt just soaking them will fill push the plunger like real oil pressure. So how do I check for the right pushrod length and geometry, if my lifter's are flat? If I use a solid, is it the same as a hydraulic lifter pumped up? Anxiously awaiting some expertise. Thanks.

What you need to do is find some soft springs/checker springs to use that will not compress the lifter and go through the checks.

I went to the hardware store and bought some really weak springs, cut and formed them so they were just stiff enough to pull the valves closed, removed the original springs from an Intake and Exhaust and substituted these. I took the measurement with the intake off using the adjustable pushrod so I could watch the lifter closely to make sure it didn't start to collapse

Adjustable pushrod and light checking springs, or you can take a lifter apart and put some coins in there to keep it at the correct height, I have never tried this so it may or may not work for you.

What about using a solid lifter? Are they the same height as a full pumped hydraulic? I'd just as soon not take apart my AFR heads, or new lifters, if that can be avoided. Thanks for all the responses.
