Hey,

Im building headers for my LS1 Iroc-z. Its going to have a TR230 cam in it, LS6 heads, and im going to have a 150 shot on it.

I have plans for more nitrous and some higher flowing heads.

Would i be best to just invest in 1 7/8" Headers to start with?

Thanks!

Sheldon

 

mine are edelbrocks there 1 3/4 stepped to 1 7/8 with a 3.5" collector. tsp just did a engine dyno with 1 3/4 and also 1 7/8 and the 1 7/8 made more power. so i guess go with 1 7/8
