Re: Setup Suggestions, input greatly appreciated!

What are you trying to do with the car? Do you need low/mid range torque/spoolup?
All out power? Why are you building a motor?

A stock 2G head will usually beat a ported 1G head in powerband and peak power until you get into some big turbos. Porting a head, adding oversize valves, doing a 1g head vs a 2g will all hurt your spoolup and low/mid range power. Yes, a ported 1G head can beat a 2G, but unless you are trying to make 800+whp I would possibly go with a 2g head. Some of the big power guys like Kiggly run 2G heads, the 2G head is closer to the Evo head, which also have small ports. Big cfm numbers/big flow make power at very high rpms/very high power but will hurt power on a 16G.

Don't get the 1600s. Get FIC 1350s or FIC 2150s. The 1550s/1600s/1650s are junk.

The normal Wiseco's have well known cracking problems, unless they fixed that in the last couple years.
