Ok guys, You all got me started on Aluminum heads. Now I’ve got a question.
I have a shot at a pair of Dart Pro1 345’s(w/ 2.30” intakes). Dart’s web site shows them for a 4.5” bore. I’m building a 454 .070”(4.320”) over with a stock stroke. Will these heads work? Looking at the block, there are notches for the intake valves at the top of the bores. Are the notches stock, or did someone have them done for clearance for bigger valves? The block is also o-ringed. The o-ring diameter is 4 3/4”.
The heads are ready to bolt on.
Also included with them is a cam and roller lifters. The roller lifters are for a tall lifter bore block. Will they work in a standard lifter bore block?
I’m set to get a screaming deal on this stuff. But I need to know if I can use it!!!
