i was running 243 heads untill the f* up . . . should i go l92/317's or look another pair of 243's???? im on a budget build . . .

this local guy sells me 317's milled .030 with a valve job . .. . ferrea valves . . for $275 . .what do u think .. .


...open for suggestions . .


im a noob on valves . . .so shine me on valves*

 

i belive the l92 supposed to fit on 4.00 bores and up only

and the 317 are the same as 243 with lower compression and better if u going to forced induction (as i heard)

243 are better for n/a

might be wrong lol

 

I would just get the 243s ported and milled.

 

agree with u

 

whats the differenc in milled and ported 243s with a valve job and the stage 2.5 prcs

 

from texas speed site

Check out the livernois 243 stage 1. I had them on my 07 and worked great, they had a great port job
