F23 into a F20B

[clutchkiickerr]

why does bisi keep refering to H22/F20B series standard valve size.... ??
theboombopshop.com refers to the valvetrain component the same way so im lost with this F20B h22 interchangeable parts aside from the camshaft,cam gear,oil & water pump, tensioner and belt are the same...... nothing about the spring ,retainer and valves are the same?? but sites are advertising the parts?? is this false advertisement? cuz i know bisi wouldnt do that

F20B valves are smaller than H22 valves. Its all over Honda-tech

i kno so why do Bisi,a whole load of websites advertise them " H22/F20B DOHC " valves for such n such...its just wierd. DO you have to call them and let them know that its for a specific motor meaning it will be for a F20B......

not the diameter, the actual stem i believe is smaller on the h22 valves. something about oversizing to fit the diam into the head, and they still just drop. like simon said, someone did a full teardown and rebuild and ran h22 valves, and some fell out after a month or so. again this is based on memory, from a while ago, actually a long while ago. im sure it would be hard to find the thread.

butt what if he uses the supertech H22 valve guides..... ? wouldnt it fit perfectly ?

you have to understand that the heads arent the same, they are close, but the stamps are different. i dont know all the difference, just remember reading taht h22 valves have fallen out of f20b heads.

thats why i asked if you were using an h22 head in the pm. the preluderacing guy, built his f20b bottom end and used the h22 top end for his 700+hp boost build. there has to be a reason some of these guys are pairing an h22 head with the f20b bottoms.

And a H22 head bolts on a F20B block( i think thats useless but to each is there own ) without a problem or the same has to be done as to a h22 head goes on a F23 bottom with sealing one of the oil or cooling holes ... idk im not sure

ok so if they are smaller, how does a h22 valve fall when placed on a f20B head, i would have thought that they get stuck but fall?? unless i dont understand how valves are placed or operate appropriately

Clutchkicker, where are you finding Eagle rods in F23 specs??? Please enlighten me. I thought the only OEM-spec rods for the F23 are Crower, and they cost a fortune. Please tell me otherwise, I'll def give rep if you can point me in the right direction for stock-spec rods through another manufacturer at a reasonable price!
