1.7 to 2056 - What heads should I consider/buy, head recommendation Options

[Gplracer]

I am restoring the 1973 914 my dad had when I was growing up. It has a 1.7L motor. I know I will need 2.0 liter heads. What do you recommend. There is a great price variance. I assume I will also need 2.0 headers among other things.

Are you sticking with fuel injection?

I built a 2056 from a 1.7 using almost all AA Performance parts. I went with 42x36 heads round port.

Part of the selection process is understanding how you plan to use the car. With stock fuel injection the limiting factor is intake runners and throttle body. My experience with building engines in the past… it can be a mistake to over size the heads when you have the other limitations.

My car is fine… it has good power the comes on predictably. It’s no hot rod… but it meets
My goals and is a good reliable driving toy.

One note… if you are using DJet make sure the know to drill and tap for the temp sensor. Also you’ll need to decide on head vents. I went without and it breaths fine. I have about 5k on the engine and it works well for me.

I am probably going to go with dual carburetors. I plan to drive the car as a weekend car. I am not racing it. So the ones you got were around $1350? I see some for that price and some that are a lot more in price so it is confusing. I do not want to under buy but also not over buy. This car was my dad's car. I want a fun peppy car and thought the 2056cc would be a good route. Jake Raby has a formula for building a 2056cc and it includes 96mm pistons and a different cam. I just power coated the rear suspension and replace all the bearings and shocks. I also did a 5 lug conversion for Fuchs which i have already purchased. I am on the front suspension now. So i have some time to research all of this. I really appreciate your time and suggestions.
