GT40P Questions

[DJJ624]

I have a set of GT40P heads and after doing research i see the 3 main problems are Headers, Valve Springs(with aftermarket cams) , and pushrod length.. The motor i have has a custom grind lunati cam in it along with 1.6 rockers... So i want to know what valve springs i need to get to prevent valve float or spring bind withough doing machine work to the head (pretty much just take the old ones out and put the new ones in if possible... Also i read the the stock pushrods are a hair to short for the gt40p's so the valves dont open all the way up.. Does anyone know what pushrods i need to get for them as well??

To figure out the springs you need to know the max lift on the cam.
And pushrold length needs to be found during the install using a length checking tool.

For pushrods, go with 4.5 inch solid titanium bars... Also, make sure you don't install them up-side-down.. You'll def run into major problems then!

Cam specs are 536/536
224/228@50 and 112 lobe sep..

So what do you guys think i should do?
