Oil restrictions to the rockers

[Sand hauler]

Was wondering if there is any way to restrict the oil to the rockers with out having to pull the heads?

[Keith Stevens]

Yes. It doesn't require head removal. Just rocker shafts. Most use a #70 Holley jet in the rocker feed for factory heads.

I thought so, but wanted to make sure,lol

Keep in mind, the jet trick is for iron, aluminum is smaller OD.  I generally tap alum, but I suppose you could do a press fit if you didn't want to drill

I had to tap my Eddelbrock heads for the restrictors. They come in POP's oil galley kit.  I think it was 10-24 and the orifice in his kit is .090.

The OP didn't mention Edelbrock or aluminum heads. I would presume they were iron in that case.

I think the OP has a couple of builds going/complete, just wanted to clarify.

Yes these are Iron. Getting a little bit of oil in 7&8 cyl. Not much. Figure it is prob from too much oil on top .
