Okay. I went back to the old forum, and did a search for the 351 heads on 302....
Found some good info. Here are a few questions it didn't answer.
I'm purchasing 70 351W heads, for $100. What should I get with it? Valves, Springs, etc?
I assume the valves would be different sizes for the intake and exhaust?
Or would my 302 valves work? (yeah, this'll show you how much I know about engines)
I know the 70 heads are the ones I want, any work that should be done on them
before I bolt 'em on?
Will the standard 4bbl intakes still fit on top there, or am I going to have to get a
351 4bbl intake to match up with the heads?
We have the engine down to the heads (the darn water pump won't come off..
stuck bolt on the right side, ARG!) and found it looks really clean. We were going
to get the 302 heads redone but after this deal came along, looks like 351 heads
now.
One other question. I checked in my "How to rebuild Ford Small Blocks" book,
and found the chart in regards to compression vs. headsize or whatever.
Originally my 78 302-2V was a compression of 8.4. I took that line across, and
found the corresponding vertical line for the 70 351-2V heads. That number said
8.7. So it correct to assume my compression will go up to 8.7 with the addition
of these heads?
Thanks guys.
