neverwouldof, you've got an excellent motor, but you should be able to build more hp at a lower rpm. That may be with a different port job, cam or whatever. Be that as it may, if you have a rear breather, block it off as HSSS427 did; your engine is set up for hydraulic lifters, whether you're running them or not. Your engine builder doesn't understand the FE needs oil to the rocker shaft (yours has it, but is it enough? You have to have enough to cool the valvesprings in a street motor; this is accomplished by the restrictors under one of the rocker shaft studs on each side) and not through the pushrods to the top end. Unless your pushrods have holes all the way through them (most for FEs don't), oil isn't getting up there as they say anyway, which is good. It's not necessary. However, you've still got a lot of oil being thrown around under your intake, so
don't use a rear breather; block it off. Use a baffle under a PCV valve on one valve cover with a hose running to the large tube in the base of the carb, and the oil-fill breather on the front of your intake as the entry point. If you need a baffle, do a search for HSSS427's post of his original problem; one is described in there, although the one he shows should work at least as well.
