Finally got all my parts in including valves springs and my new intake for a 24 mm carb. Ive come to notice though that the new intake valve takegawa sells is 28mm compaired to the 27 that the older super heads have. I even called lyle from CHP to get his imput. He said the size differences is considered to be worth 4 sheets of paper and i shouldnt have anything to worry about. Also according to my parts numbers they are the correct ones for my head. My question is has anyone else noticed this before they put there new valves in there older super heads.
If anyone has the older takegawa cataloge and could do me the favor and look up there part number which is 14711-SPR-T00 Was this number considered the replacement valve for the olderstyle super heads (not plus Rs)
And on the CHP website its P378IV.
Like i said lyle told me i shouldnt have anything to worry about and as im understanding takegawa basically made a once size fits all type of deal (maybe to save money?). Ive already put the new valves and springs in and everything seals up perfectly when i do a leak down. Im just a lil concerned about the valves hitting the piston so i may grind out a lil extra space just in case on the inlets of the valve reliefs on the piston.
What is the serial number on your head?
