Valve Recommendations

At this power level, replacing your OEM valves with aftermarket valves is a must! An aftermarket valve is constructed of materials that can withstand the heat. Aftermarket valves bend, OEM valves break.
Is a bigger valve better? Nope, we have made 1400whp with stock size valves. Also an oversized valve does not fit on the exhaust seat, because the larger valve is bigger than the valve seat.
FUN FACT! Oversize valve will flow less than the stock size valve up to .350 lift (9mm). This means that you will lose more than you gain going to oversized valve when using a cam under 10mm lift!!

A common concern when picking out a spring kit is adding too much spring pressure, especially in street applications. When it comes to the spring, more pressure is better than less pressure. Less pressure will result in valve float which can cause damage to your valve-train.
The correct amount of pressure will keep the springs controlled which in turn controls the valves. The number one cause of valve-train and or cam/bucket failure is not having the correct valve spring for your application. If the valve spring is not happy, nothing will be happy.

Are you planning to sit in a lawn chair and listen to your car? If so, purchase the biggest cam on the market and you’ll be a happy camper! The big chop will add happiness to your ears, but it will feel laggy because the camshaft is too big!
If you enjoy beating the crap out of your car and jumping into boost, a smaller cam is the cam for you!
Anything from 550-700whp will benefit from the added lift and duration of the GSC S1 cam.

Buckets (aka lifter valves) are wearable items. The number one cause of valvetrain failure and or cam/bucket failure is not having the correct valve spring for your combination. If the valve spring is not happy, nothing will be happy. DLC won’t save you, it will only take longer for the failure to happen.
If you are shopping for heads because of a recent engine failure, it is likely your bucekts will need to be replaced. Especially if you are upgrading to a new cam.
HeadGames can polish them, if they pass our inspection, great! We will not reuse buckets that have any kind of wear, this is a recipe for failure.

If you’re making less than 550whp you can get away with no port work, our rebuild with guides service will give you the reliability you are looking for.
If you’re making 550whp up to 700whp we often get asked if a full port is necessary, the answer is no! A full port has too much port volume and will hurt the area under the curve under 700whp.
Lucky for you we offer a budget-friendly upgrade, known as the pocket port! It will give you the ability to make more area under the curve and at a lower boost level so you don’t have to push your combo to unsafe boost levels.
