all advices and appreciated! continue...
well i my afr heads came in they are 225 i knw they are ready to run out the box but for any reason should i have any porting done? |
Wouldn't hurt nothing. As a general rule of thumb, you can get about 2hp per cfm if everything else in the world is up to snuff. Those heads flow about 310-315 at a modest valve lift, so you can support over 600hp with those. However, the more flow you have (especially while keeping the same CSA) the better, and it will keep you from having to make the horsepower with the camshaft.
Those 225cc heads are good size....you'll want some big cubes to take advantage of it and not make it doggy on the street. Smaller displacements will have trouble getting good air velocity from them with street rpm's. I would start looking at displacements of 427 and above. If you plan on going smaller displacement for some reason, I'd leave the heads alone and not port them. |
Brent...you should take a look at volusion and think about converting that website into a store.
