914-4 2.0 Ti Valve Spring Retainers, Valve springs?

O.K. here we go again.

1975 2.0L Stock injection and 73 Exhaust.
96mm pistons.
WebCam 73. 00-472
WebCam lifters. 00-263

Heads are going to be redone. New seats and Stainless valves. Due to Previous work, oversize valves will be probably be used, with minor porting to blend the bowl to the seat.

Thinking Webcam single springs? VS-POO or Dual VC-PO1

Who makes a nice Ti retainer? (lighter and my retainers and springs are suspect.)

Not yet. In the "gather parts" phase.

We bought the Titanium retainers, dual springs, etc from Crower Cams in Chula Vista CA and they have a good website and we use a Crower cam too. I thought Webcam had Ti retainers too? Good luck.

I was not able to find the Ti retainers on webcams site.

the dual kit includes Cromemolly retainers.

Mind if I ask what the part number of your Crower cam and springs/retainer kit are? They seem to only do TIV cams on a custom order basis.

I'm assuming that Type1 springs and retainers are not the same/won't work?

Point taken, I just figured If I'm buying it wouldn't hurt.

what is the price difference for a complete Ti kit (retainers, springs) vs a quality chromoly kit?

I haven't found any TypeIV Ti ones yet, so its impossible to say. 25-50% on Chevys, Fords and BMWs.
