Contour Enthusiasts Group Archives Forums Modifications Duratec Performance SVT uppers, lowers, and tb on a 98 se

What up all,

I just got my svt parts the other day and have been busy getting the tb polished up and the shaft trimmed down. From what i understand the svt lowers (from a 98 svt) are about 1mm dia larger than the se lowers (98.5 se). So obviously i need to do one of two things:
1.) Pull the heads and have them portmatched to the svt lowers
2.) Have my se lowers blended to match the svt uppers and probably swap or remove the secondaries

This is my only ride at the moment or i would go with option 1 no questions asked. So I'm mainly looking for input on option 2.

Any thoughts?

The head ports are cast larger than they need to be and will match the SVT lower just fine.

Thanx B.

I was just looking at the svt uppers and lowers and noticed that even the se upper to lower gasket has port openings a mm or 2 larger than the ports on the svt manifolds, so.... I guess it just comes down to how meticulous you want to be and how much free time you have anyway...
