Ooo ok lol I'm upgrading the valves from the stock 178-150 to 188-160

you know what, my bad...I keep thinking 360 heads.

Just know you can easily get 215 cfm with porting using the 1.78 valve, but the 1.88 should make it easier.

on the 318 exhuast...thats a good port, i get 145-155cfm easy with porting and valve job.
