Solid roller lifters...

OK so I managed to find BAM 2016-16 available at Hughes. They can be upgraded in the future to brass or steel bushing for 500$ and also pushrod oiling hole can be plugged to better control oil pressure. I will report what I get after I install them.
Now just waiting for camshaft.
Spring wise I got PAC 1225, they will be 260lbs seat and 760 lbs open.

Did any of you guys have experience with older .750 wheel BAM lifters?
