How does this sound...
...Eagle 3.25" cast steel crank
SIR 5.4" I-Beam rods
SRP forged flat tops....to start....
Then...
1.7 Comp Cams roller rockers
Canfield Heads, 1.94/1.60 valves
...maybe shave a little off if needed as to get
down to 57cc chambers...
...so to keep compression below 10.5:1 for pump gas...
Hyd. flat tappet:
.587/.587 228* duration @.050
I know.....but...I already got 2 motors in the garage...

a 331? id go 347 or stay 302, canfield has good heads, not the cheapest by any means.
The dynamic compression is more important than static, the cam size and rod has a lot to do with it, and aluminum heads will help.
I did build a 331 once but we got a good deal on it. I had to notch the bottom block bores, for the nut to have clearence.

Cylinder notch...
...that's whats got me thinkin'...
Was it 'cause of the rods you used or just the 331" kit overall?
I was hopin' that maybe goin' to an H-beam rod "might" get me
around that...
By the way...have not been able to pull up the Canfield website
for a couple days now and the phone just keeps ringing...

I like rhs heads they offer good value and flow. The nut on the rod bolt so so damn close to the bottom of the bore, so i clearance it slightly not a big deal. A capscrew bolt would most likey be fine.

...Kool...that is what I was thinkin'...thanks...
Which 331 "kit" did you use?
The only reason I was likin' this setup is 'cause I spoke with a
dude that has done this & it's been on the street for about
5-6 years and still haulin' a$$...in a vintage truck...
With occasional 1320-passes...

If you use the 1.94s for a mild street app with a .587 lift you should flow pretty well with those heads. If you go too large the air velocity you want won't be there for fuel suspension. Make sure your seats and valves will be cut accordingly for optimum flow.
Thats a good reason, its dependable!

1.94 valves in an optimized port are fine. I have found that stock ford heads usually like bigger valves, but 2.20/1.60in sbf literally touch. The seats leave a super sharp ridge where they meat and is a great place for cracks to start. Nascar pulls 400 cfm with a 2.15 valve by the way.

Great info...
...thanks...
I know that Canfield's owner has reciently decided to go into retirement
but...I ran across THIS earlier this morning while researching cylinder heads...
...
HOT ROD WHEEL COMPANY / CANFIELD CYLINDER HEADS - Myron Bowling Auctioneers
Good for him...obvisously he has enjoyed a very successful career...bad
news for me...I DO know that the Canfield Part #20-450-58-1 is very
similar to being and basically an AFR165 equivalent...
FWIW...

Thats true John Fenton owner of canfeild has closed its doors, John has retired.
Be careful buying older canfeilds as they were prone to cracking and some other issues.
Trick flow 190 fast as cast heads, would be a good choice can be used for small blocks with room to grow to 351 engines, cam accordingly to your application.
With either rod you choose you'll still have to notch the block accordingly.
