I have a SBC 355 Gen 1 block machined for a 383 stroker build. These heads are great but will they match the coolant holes of the Gen 1 block? Its important that engine can cool itself with radiator fluid. Or will this need some special by-pass?
Can I run the Lunati Voodoo Hydraulic Flat Tappet Camshaft and Lifter Kit Chevy Small Block 262-400 Lift: .504" /.525" with heads? Part Number: 638-10120704LK. My concern is springs.
What do I need to do to be able to run Lunati 73943 valve springs on the the AFR head 033-1034? or are they compatible withe the supplied retainers?
