Exclamation 4v Heads on a 2v motor?

Ok, so i have a chance to get a set of 4v heads for pretty cheap. My question is, will they bolt straight on to the Bullitt 2v motor (the bullitts have a different intake and manifold than the GT) and if not, what else do i have to change to make them work?

the 4v heads will work with your block, but you'll need the proper intake depending of which 4v heads you got...

i absolutely can't claim any expertise here but some things i'm pretty sure you'll need are:

valve covers, front cover, full timing chain set with sprockets and tensioners, 4v computer and harness, intake manifold and maybe entire air inlet including maf and TB

good luck with it

for the experts here--please feel free to add or correct me if i got it wrong

You can use the GT computer if you don't use the knock sensors they have. But yes they do bolt onto the 2v short block.

The compression will be down pretty low... like turd on the street low. I would recommend some pistons from a cobra short block or something aftermarket to get the compression back up. Youll need an intake and timing cover. you can use your factory computer but you may have to extend a few wires.
