What heads are on there now? Every thing is still a stock '70' 302? May not be worth the time and money to swap the heads.

I'm guessing they are 351 Windsor heads?
If they are you might get a little better performance out of them but not a lot. If they are Cleveland heads though, then yeah, they're worth the swap.
What is the casting number on them?
Also, you might try posting this in the 'Classic Talk' section to get more answers...

the gain vs. the money spent is not worth it

a stock set of 351 head are not any better than the 302 heads...

my advice save the money and put it towards a good set of aftermarket heads....

i was under impression that truck 351w would have bigger ports than the e-7 little play toy heads.
