Question On heads

[boostmaster]

Just wanted to know if a set of unported 1.77 / 1.50 stainless valve heads would make any significant difference over stock valve heads? And if so how much?

Thanks, Pete

From what I have studied there will be no noticable difference.

I don't think with how bad the stock ports are it would help at all.

Agreed.

But if you are going to get a set ported the set with bigger valves will be a better starting point.
