Si head on a HF?

Would it be hard or is it possible to put a Si head on a HF Block? I was just wondering since the HF is 8 valve and the Si is 16 valve. If anyone knows if this is possible please let me know. It's for a friend of mine that just bought a HF and was wanting to use my old Si head.:D

can anybody help???? :confused: :(

I don't think that would work since the Hf and the Si are different sizes.
HF - 1.5
Si - 1.6
You could bore over the engine but then you would have to put in new internals also. Well new piston heads atleast. Seems to me, it wouldn't be worth it. To much work for to little gain.

BTW Nice avatar. THIEF!!!! :mad:

it works...I've seen it done.

everyone always says shit about the valve reliefs....but it works.


ps...I've got a head layin around if ya want it ;)

It works? Wow!! :eek: That's pretty cool.
What kind of gains does it give?

Not much..but the hf is lighter than an si so he has the weight advantage :)

So it will for sure work? Since the HF is only 62HP, will the Si head give it anymore HP? Just wondering. Thanks

P.S. Sorry, didnt mean to steal your avatar. Didnt know u had it.:licker:

You didn't know I had it? Then how did you get it?

I got it from a website. I saved the picture and decreased the pixels to 100x100.:rolleyes:

Oh really? Then how come it's photoshopped exactly like mine?

DUM DUM DUMMMMMM shut up you 2 sound liek two old women

Well anyways...this was a thread to ask a question about a Si head, not to bitch about avatars.:rolleyes:

And your point being???

LOL, nevermind. This is too funny to me.:p
