HE! HE! HE! Well Dave you think this will get any of those little head chevy lovers going.

hope not me my heads just have a 2.400 valve

I used to put the 11/32 Ford valves in Chev heads with guide liners to save weight.

The last valves I had for my heads were 2.475

On the 392's we couldn't get past 2.100x 2.000 or they would hook together on overlap--with the Donovan alum heads changed the angles and eliminated some of that

just cut some ti valves 2.350 down to 2.325 and 1.900 they get close with a bbc 360 dart START RUNNING OUT OF VALVE SEAT CANT HANG THE INTAKE 45 ON THE EX SEATI JUST CUT down SOME BBC INCONEL VALVES FOR THE 37 CADDY works good i hold the valve in a 5C collets

Ya But arn't those BBC Valves!!!
Mine is a small block Ford.
Also did they come from the factory with those big valves?
My small block did.

big valve s are not every thing . them 351 c heads get the A &B putty JoB ports are to big . yes my heads came with 2.400/1.900 .most bbs are 2.065/1.725 not hard to stuff a 2.250 /1880 or 2.300 if you feel the need

I know Pat; just messing with the chevy guys.HE! HE!
The only thing the big cleveland heads are good for is all out racing.
For the street the 2.05 are much better, I know they started building the
cleveland engine when the emmission crunch came in to play.
Then they did away with leaded fuel and dropped the octane in the fuels.
Back when it was built though I was still able to buy about 112 octane and higher
from union 76. At least thats what I was running in my old BB charger with 11.5 to 1.
Today unless your racing it all the time, the big valve cleveland heads are not very pratical.
Kurt
But my point is them big valves still came in a small block Ford.
HE! HE! HE! Not a big block, but a small block.
Chevy lover.HE! HE! HE!
Just kidding Pat.

WELL...... it s funny that the 351 head looks alot like a BBC head used the same rocker arm as a bbc if you go roller rocker the hp bbc came with 2.190/1880

Ya the car guys have been stealing each others ideas for years.Just like everyone one stoled the power steering and power brakes, form the Dodge brothers.
Maybe I should say borrowed, Ya thats it ford borrowed the head design from Chebby.
Thats the ticket. Kurt

....... yep

Vara, While I am mostly an early Hemi guy, I do love them Chevys as well. Now with that said credit needs to go were credit "Really" belongs. That would be true of engine design as well wouldn't you think?

There is only one American made engine that ever won a "World Championship" only one. Care to take a guess ????

The Ford 289. Its the one and only when it comes to that...

RS

Thats news to me, I'll have to stick that under my hat for a rainy day.
