Sure - just need to drill out the head bolt holes to 1/2". I set mine on a piece of plywood and drilled them in the press in two steps..

There's quite a bit of information on these if you look around a little.

+1 you do need to drill them, but they can and should be used. Gt40/40p stuff is great for cheaper builds.

ARYANW

ok great.thats what im doing..a cheap build.so just drill the holes out to 1/2in.

So nowwilla 302 upper and lower EFI intake bolt up?

no cause they will still be to wide considering it is a 351. it would be the same as bolting up a set of stock 351 heads on the block. you will still need a 351 lower. and you will need a 351 distributer since the bearing on the 351 is bigger than the 302.

i understand..but i dont.lol sorry im new at all this and always learning.soo if the gt40 heads came off a 302...and a lower intake was bolted up to that..why wouldnt it work now?

the deck on the two blocks are different and that is where it comes in.

ok.im just rethinking things because some guys at work are telling me to EFI instead of carb.idk what to do lol
