6.1 with thitek heads or stock 6.4 with ported heads

[11.2]

im thinking about a swap. found a built 6.1 but wondering how it woukd compare with a 6.4 with ported stock heads ?

More info on both combinations would be helpful. Both cylinder head options are bad mofos that make really good power.

This is the info I have, looking at buying this or buying a stock 6.4 and doing some head work but the 6.1 would be an easier swap

That's a real nice build for the 6.1. What about the 6.4? Just stock with ported heads? Cam swap? Etc.?

Yes. There is a low mile 6.4 for sale. It would end up being similar in price by the time I got the 6.4 worked on but the 6.1 is all forged and I’ve heard those heads are crazy good.
The guy with the 6.1 claims 500hp to the wheels, I can’t seem to find any dyno numbers or time slips with similar builds.

He is probably not lying. Those Thitek heads are STUPID good.

Yeah, I’m really leaning towards the 6.1 because of those heads

Guess it might depend on budget then? 6.4 is no slouch either. If you can get the 6.1 for not much more, then it's a no brainer.
