Engine build

[3vbeto]

Hey guys I have a 3v 05 gt, and want to build a motor for it, I received a free f150 4.6 2005 block, it’s cast iron block, I want to know if I can use 3v heads on it since it’s a 2v and if it’s worth building and swapping, I want reinforced internals , bore etc

The 3V heads should bolt straight on. Although the cast iron block will add ~60lb more weight at the front, it's a good choice if you're planning to add forced induction.
