Edelbrock valve spring replacements

No, I simply pointed out that each of those springs is in the same ballpark as Comp Cams' 928-16 spring, which has 190lb on the seat at 1.800" and a rate of 354lb - and is the suggested spring for all Comp Cams drag race and oval race mechanical flat tappets for the LA Engine.

If you don't want to machine the spring pockets, then I would look for an LS spring that matches whatever the cam manufacturer recommends and see if it fits the bill.

Incidentally, this thread is about fitting springs to Edelbrock heads without machining. I don't need to repeat myself - all the info is contained and is correct regarding the use of LS springs - and I am not recommending beehives to anyone. They are just the spring I use in my application and they have worked very well. You can all do your own homework now.

I know, i have eddies on my motor and just set them up last summer.
Those spring pressures you mention are too much for flat tappet cams in most cases.
The guy who specced my springs is a comp cam dealer and well known Mopar head porter/ engine builder. He didnt want anywhere near that much spring on my cam, and its 260@50 and would be considered a race piece
