Pushrod question

So after getting heads on . Johnson 2110 lifter , ls9 head gaskett , I measure with the pushrod length checker . I came up with 7.36 that with Johnson preload already added of .035 . Pushrods only come 7.375 is the closest one . I know there’s a +.010 if variance that’s allowed . Which puts me tad over . Will that be a issue ? They do offer a 7.35 which puts me right at the max variance at -.010. Which direction should I go ? And if possible what’s the pros and cons . Thank you really appreciate any feedback

Definitely a question for Andrew at GPI. He's the guru around here with cams.

Talked to Johnson . They told me they would prefer to be on the tighter side , as aluminum motors when they get to running temp the lifters loose .015 of preload . They also told me they want me to measure all cylinders int/exhaust instead of the two I did on each side .

Makes sense. Measuring each cylinder is good practice too. Better safe than do it twice or get a new short block.

Yeah, I have seen some people having to run multiple different pushrod lengths. What a pita that must be to keep track of.

No doubt about that, sounds like a real bundle of joy. I bet you only get them mixed up once, pistons and valves don’t appreciate cozy time much.

I bet that would be a pita . I figured tho with the lifters have some travel , I think .200 of travel figures it would all
Work but , when i have time I’ll measure every single one .
