Hey everyone,

So, my brother has a 1977 f150 with a 400 in it. He bought some Chinese speedmaster 4v cleveland heads for it but his intake doesn't work with the heads. I would say that he could run spacers and a 351 intake but the company that used to make them is no longer providing them. So, if anyone has ideas, that'd be great.

Also, if there's no way to make this work economically, he does have a set of mildly ported 2v heads he can use. He just picked his cam off of the 4v heads so it's quite the bump stick and I don't think the motor would run great with the 2v heads.

Thanks in advance,
Deacon
