Hmmm... what are the valve sizes of the two? If they're the same valve sizes, but the different flowing capabilities (which I think they are) than it'll all depend on the cam.

Don't quote me on this, just trying to help. I'm sure someone'll back me up here if I'm right.

EDIT: I just checked AFR's site, they both have the same exhaust valve (1.600) but the intake valves are different. 2.020 for the 185's and 2.080 for the 205s and 225s.

Oh, no no. The valve size that comes on the lightning won't matter, its the valve size of the new heads that will matter.

The 205s probally will work with the stock or another very small cam,but why would you want that combo?

he runs 110 oct. gas too with stock motor besides this sn-95 blower with 8 lbs of boost. i dont know why. he just does. he thinks its better. i think its a waist. but he wants the badest AFR head he can put on there. i think 185 would be the best. he thinks cause i say this that i'm scared if he gets 205's vs. the 185's.

205's and a stock cam will run like trash..... There is no point. Those heads arent meant for an otherwise stock engine.

Let him do what he wants, and when it does run like shiit then you can let him have it..

FWIW I doubt you will be able to fit the 205 head anyway.

Give me HEAD till I'm dead
