Looking to upgrade my heads. Any suggestions on a good set? I have a 408 nitrous motor; iron block, spraying 300-400 shot. It is hyd. roller, but thinking of going solid roller when I get the heads. I have a ported super victor intake now,Shifting at 6900. 530 to the tires on motor, with the ported TEA 5.3 heads. best et is 5.65 @ 121mph....leaving on a 300 shot, this is with 1 3/4 header just bought 2" kooks...end goal I am wanting to run 5.40's.

Give Brian Tooley a call. TFS 245 and a nitrous cam from him should get you where you want to be.

Either the AFR or the TFS heads would work well. I think the TFS 245 heads would be a little better than the AFR's, but you really can't go wrong with either.

Those would be a great choice. Hit up Brian Tooley, he'll get you setup right.
