New Build - 4G64 2.2 Long Rod
#16
What fuel???
If you're looking at E85, the 1300cc injectors might be a limiting factor.
Maybe look into the R2 cams if you're looking at pushing the setup.
Also there is nothing wrong with the GSC5041 valve spring kit either.
Anything below 800whp, stay with stock sized valves. 1mm oversize will actually lose flow unless you radically change the port shape.

Sounds similar to my build I have going on. 2.2 4G64, 10:1 compression. I'm running Kelford 272s (would like to swap for GSC R2s but money) and I'll be running Wiseco 1400s, ER oil pump gear and MIVEC gear mod. Car will likely be E85 99% of the time but I'm still planning on a flex fuel tune.

Spot on mate! That's what I am going to do
Headgames is in my mind. The thing is that I am in EU and I want to visit one machine shop for all machining jobs. Not sending the head to one machine shop, the block to another machine shop & when something goes wrong each shop will blame another. You got where I am coming from.

Make sure you get the full length valve guides too. Shorter guides reduce valve cooling and wear faster because they allow more runout.
1300s will def be on the small side for a 6466, consider getting 1700s instead.
I can echo issues with Sheepey as well. I have a local friend who got shipped a manifold with the wrong turbine flange welded on and it took them almost 3 months to admit they ****ed up and fix it for him.

I am considering the R2 as well, but definitely it will be something from GSC.
As for the springs totally agree, there is nothing wrong either with GSC or Kiggly Racing.
It will be around there the wheel horsepower, as of the valve size, the builder & the machine shop I assume they know better than me so I will leave it on them.

Give me a follow on insta if you want to discuss it further & exchange ideas since we share the same built. @alex.evoix

Good head shops don't usually do bottom end work and machine shops that do bottom end work won't port a head as nicely as a head shop that specializes in a particular head like Head Games does with the 4G.

As for the valve guides, thanks for letting me know. Didn't know that. Do you know which brands offer full size? or it comes as an option when you order them?
I think both 1300s & 1700s will work fine.

Am considering Head Games but I will see, as I am located in the EU as I mentioned above. In EU there are some good shops as well.

ID1700 is more like injector that you use on E85 and run pump gas occasionally
If you run out of fuel flow, you can run higher base fuel pressure if your pump is powerful enough or run a second set of injector

For pump gas, you are better off going with 1300CC as they are designed to have optimum idle & low speed drviability for pump gas
