I want to say that standard TW heads start running into geometry issues over 0.700" lift. I don't know if the 11R heads have the same issues as the older versions.

I think your goals are achievable with the TW heads, but would likely be easier and less troublesome with a set of bigger High Ports. If you absolutely need the TW heads, it wouldn't be a bad idea to check with TEA or Fox Lake about their Renegade heads.

I also agree on the compression. At 12.5:1, you are going to have to buy good fuel anyways.

You might need some Titanium rods and a flow bench!  LMAO on floor

Even for equal horsepower, the bigger the displacement, the bigger the heads need to be...  and vice versa.  Bigger cubes take a bigger gulp of air.  Smaller cubes will turn more rpm, and take more 'gulps', but each gulp will be slightly smaller...  and not require as big of a cylinder head.

In other words, you'll be better off with those heads on a 363 than a 408+.

Good Luck
