I just want to cut 1.8's and thats it. I was going to put some 555's on there but I heard some horrible stories about there end results.

So i'll leave it up to you.

Heads for 1100, installed and dyno tuned (i know a guy). The setup should be making around 350 rwhp. staying with the nitto 450's.

Or stall with nitto 555's.

Which sounds safer, and would yield better times?????

I think the stall and drs will net me better 1/8th mile times and slower 1/4s. And i dont think it will hold up as long. I think rearend would go

Heads slower 1/8th but faster or equal 1/4s. Safer. I think tranny would go.
