L98 Cams
L98 Cams
What type of cam came standard in the L98? Was it a hydraulic flat tappet or hydraulic roller?
Also, does anybody know what the dimensions of the valvesprings were on the L98 aluminum heads?
And one last thing....if anybody knows where to find the flow dimensions of the L98 aluminum heads, that'd be much appreciated.
Thanks guys.

Hydraulic roller.
I believe they were 1.25" OD valve springs on those heads. I'm about 95% sure of that.
There are flow values for those heads floating around the internet, even on this very board. They aren't very amazing though, i'll warn you now. The casting number should be 113, so search for "113 flow numbers" or something and see what you find.
