BSmoothXTR Posted November 27, 2012 Report Share Posted November 27, 2012 Here is the situation... I have scoured the net and came up short. I am in the process of having my '86 Z24 from my 720 being built... the wall I ran into is I need intake vavles, exhaust vavles, springs and retainers. I don't want to buy stock parts... but I can't find aftermarket stuff. Main question is, do the KA24 parts fit these locations on the Z24? If so, I have plans to get them, but don't want to make a huge mistake wasting the money if they don't. I would like to do more research myself, but I'm currently deployed to Afghanistan, so I really need the help. Anyone know anything? Thanks Quote Link to comment
ggzilla Posted November 27, 2012 Report Share Posted November 27, 2012 Yes, if you want to put smaller valves in. KA has 3-valve or 4-valve heads (smaller valves, but more of them). Guys have used Chevrolet valves, grind down the length and bore out the valve seats. Have you considered putting money into a KA? A stock KA will outpower most built Z24. Quote Link to comment
datzenmike Posted November 27, 2012 Report Share Posted November 27, 2012 All Z20 Z22 Z24 intskess are the same size I believe. Except the 720 Z20 Mileage Option motor. You want...13201-N8500 look them up for sure. Just find a used head and strip the parts you need. Unless your old valves are burnt, bent, broken they can be refaced and ground to fit new seats.

ggzilla Posted November 27, 2012 Report Share Posted November 27, 2012 That's a stock part number isn't it? I don't want to buy stock parts Quote Link to comment
I'm BLUE Posted November 27, 2012 Report Share Posted November 27, 2012 If I may ask the purpose of wanting larger valves ? Overall engine plans/parts ? Thankyou for your service. Quote Link to comment
datzenmike Posted November 27, 2012 Report Share Posted November 27, 2012 I think he just said valves, not larger. I don't think there is room for larger (or much larger) on a Z head. Yes stock number. Quote Link to comment
