hello guys
im rebuilding my 1964 394,and just received my parts.
but the new lifters are not the same as the old one's.
the new one's have a small oil hole on top,and the old one's dont.
my pushrods are solid
when i close the oil hole on the lifters by a solid pushrod,can the lifter relieve its pressure?
ore does it keep building up pressure,so my valve's dont close?
ore maby its better to get some open pushrods?

its the last thing im wondering about,

and then after almost 1 year of rebuilding,,,,,,,,,,,,,,,,,,,,,
