From building Ford strokers for a few decades and the last 5 yrs having lifter/cam issues since ALL builds have roller cams, I will not use anything but Howard or Johnson, that said the last one I put together I tried USA made Isky. No issues so far.
I would not use ANY lifter unless it's Johnson, Howard or so far Isky.
Ford Performance lifters were decent. Last 8 yrs are crap. NO Ford Perf, No Summit, no Comp products.
High quality lifters are $1,000/set. Yeah, what happened right???
Lifter failure is the #2 most expensive repair for internal combustion engines.
These are my experiences and I won't spec or assemble an engine w/o roller lifter/cam.
