Hey everyone, hoping to get some insight and clarity on couple of questions!

I’m in the middle of planing/building a 4g63 project to hit 1000-1100whp. This is my first time building such a high horsepower engine so i do not want to throw expensive parts at it without any idea of limits.

1. Headstuds- will M11 CA625 be sufficient or should i switch to 1/2inch?

2. Headgasket - HKS or Athena cut ring style headgasket is enough to hold the cylinder pressures?

not really set on the turbo yet but thinking of 7675 or similar

3. lifters- can the hydraulic lifters cope with 10-10500rpm or should I go with Solid lifters?

I’d really appreciate your input and thoughts!
