Check out some of the SVO aluminum heads from FoMoCo.


I prefer factory parts.

 

Alright... well what size should I be looking for?

 

Agreed, if you went through teh trouble making a 408, why would you stick patriots or 'pro-comp's on there..

 

It depends on your cam/gear/intake setup.

 

Cam is aggressive, I can't remember what it is butit dies around 1000rpm, gearing is 373's behind a T5 with 3.35 1st gear and .68 OD, Elelbrock Performer RPM intake

 

Canfield

 

bang for the buck id say edelbrock.

i just got mine in the mail on wednesday. and im gonna port em a little before i bolt em on.

 

Cool! How bout size though? What should I be looking for?

 

i have afr 225's on my 408

i'd love to be able to rave about how great they are but since they ate the t-shirt all progress has stopped.

AFR sent the wrong replacement valves and the correct ones are on a world tour with the Olympic torch or something...its been 2 months[:@]

I will say the 225s are race application and i think they will be too much on a street engine.
I will also add that AFR's dont helicoil the bolt holes for your headers and they are very soft.

 

uuuuuummmmmmmm knock knock any1 ever heard of a clevor de da de, yep i went there but you have to admit that the heads (with a little work) are some of the best heads ever (clevelands) the only problem is an intake
