I know you've probably heard it a thousand times...

Listen, I KNOW that you will all probably hate me for asking, but i CAN NOT find for the life of me in any message board the specs for the STOCK cam and heads of a L98 AND LB9....what i've found so far....i think the L98 has the 083 heads? and the LB9 has the 081 heads? ok what i do know...and correct me if i'm wrong

L98 heads:
64cc cast iron or 58cc aluminum...
i don't know the porting of the valves...

LB9 heads:
58cc cast iron
no more than that

L98 cam:
i need to know everything there is to know

LB9 cam:
nothing i am sure of....

as you can see i'm very lost and i find different specs for the same stock heads....so my searching methods SUCK. ANY info would help so much and i'd love you forever! thank you in advance...

Toward the bottom of the page.

As far as heads, look a few posts away from this one.
