In my case, all the lifter bores were checked before assembly by the engine builder and found to be
" well within specification".
I have learned my lesson I will never again use any type of roller lifter for a street application.
I've never had any issues with a roller lifter or cam. I recommend solid roller to those who have had issues with hyd retro in non roller blocks.
Maybe this is the diff...
Unless it came with a hyd roller... I wont use one. I will only build with a hyd roller if it's a factory roller block and the factory hyd lifters and spider are used. Period.
