okay, so i've searched and read the the two center bolts will be at a different angle, and that they would need shaved down to capacities. basically i'm wondering if those are the only two problems, how much of a problem the center bolts is, and an exstimate on how much the shaving would cost.

thanx,

Any particular reason you aren't just working over your LG4 heads? Other than chamber and intake valve size (along with the bolt differences you mentioned), they're the same heads.

No particular problem with centerbolt covers. They seal better than perimeter bolt covers.

 

well, i'm pretty sure their warped, and i'm not sure how bad as i havn't had time to take em off yet. (and yes, i'm going to take time to check before i went and spent money on any of this :P)

just looking at options mainly

 

Well, I'll try to list the pros & cons of each that I can think of:

L98
Pro:
1.94" intake valves

Cons:
Need to be shaved about .035" to reduce the chamber size
Shaving heads that much requires shaving the intake

LG4
Pro:
Proper size chambers
Clean-up shave won't require shaving the intake

Cons:
Expense of installing 1.94" intake valves


Both heads need something done about the press-in rocker studs if you put a healthy cam in. Both benefit from some clean-up porting, especially the valve bowls.
