Stroker 340>416 Build Advice

Generally no. But if you don’t know what to look for and/or lack the tools to do so, the cost isn’t much for a machinist to check out. He could also, for a few bucks more, tweak the valve job and/or do some bowl work to further enhance low lift flow which is most important.

The ones my wife bought were really very nice in there OOTB condition and perform very well.

The Edelbrock also falls under the above. My last set was nice. There good for around, give or take, 475/500 hp. But it will be a little harder to achieve against the TF head because the flow less. Calculate the added expense of porting the Edelbrock head to match the TF head and I think you’ll find the TF head is advantageous to purchase over the Edelbrock head. Valve gear is also a consideration expense.

Whwn all is said and done, I like the TF option for better performance and a higher performance ceiling.
