FPR, Valve cover, Cam, valve springs ?

These components are not all specific to the head, and the cam is different. However, I'm looking for something a bit more specific on the springs.

THey only used single valve springs instead of double.

e cam used only part of the journals and the super eta head doesn't have oil passages drilled for the unused journals.

I'm pretty sure they used dual valve springs since the rpms were raised for the eta. I think around 6000rpm the e valve springs will start to float, but i'm not sure...

Good call on the 4 bearing cam only needing 4 oil journals.

Nick: Super-Etas have single valve springs.

Actually, the super eta head uses all 7 cam journals and all are drilled. The head castings are identicle to an "i" casting.

Trent was the first to really nail the valve spring portion of the question so its his turn. The outer valve springs are actually the same part as an "i" outer valve spring. Its just missing the inner spring. The cam is the only other difference. Although its an eta cam, the journals are all there, and all are drilled for oil.

Your call Jordan, but I think Trent was more accurate given the cam difference was already answered.

I'm not playing... just making sure info is straight.

Okay Jordan, then Trent it is. Go for it Trent.

What is (roughy) the rate in lbs/inch for an "i" valve spring combination (big and little spring)?

Great...looks like i killed this thread. Sorry for the stumper guys. The spring comination averages 190-210 lbs/inch.
