the intake is a cut and shorten 360 dodge 1.88" valve. the ex is a slantsix intake 1.62" reduced , i am now having a set of engbilder valve done,their 1 piece s.s. valve are nice. the intake is a 1.81"bb dodge ex valve that needs to be shorten and keeper groove recut. the dia is pretty close so you can measure to see if they clear. i am having it reduced to 1.80" so it will clear my .080 over bore. the exhaust is the 1.70" slantsix intake that is the right lenght just needs the have the dia reduced to 1.60",now with this exhaust size i had to use a fine stone and put a clearence notch in the top of the bore, .030" should be enough, my front three cyls would clear without the notch, 4&6 just missed and 5 hit. i just did them all the same. just mark the highest point of thavel for the top ring and don`t go handy to it. works for me. engbilder wanted $38 for the 1.70 slantsix and $66 for the 1.81 bb dodge ex valves. |

i forgot to say mybe you could go to 1.58 or 1.55 on the exhaust if you don`t want to notch the bore, just measure with the head on a bare block and go from there. now the engiblder 1.70 and 1.44 valve weren`t bad i did go 11.48et@115mph 12psi boost. |
