replacing stock head with slant head?

[zippinaround]

I was going to replace my stock head with a slant head however my stock one had 6mm holes the slant has 8mm and it only just squeezes on! just wondering if this is a good idea or a bad idea? i'm pretty sure my piston won't hit the head with just one base gasket and one head gasket. my piston only comes level with the cylinder and is flat. any input appreciated...

Looks like you are installing a 66 CC head on a 48 cc
Why are you doing that?

thats what i was thinking! is the stock one definitely 48? the guy i bought it from said it was 66 and i have never checked so my bad.

Flat top piston,,, 48cc. Cheerz

Never even seen one of these in real life before I bought this one! So I just took his word for it. Thanks for the help

just out of curiosity what would happen if i had run the engine with a 66 head?

Less compression-less power.

And probably a head gasket leak.

I like the straight plug heads better anyway. all the engines i've built are faster and rarely blow gaskets.

the angled heads warp, have less cooling, and the only advantage to them is if your motor doesn't fit with a straight plug. all the performance claims, from my experience (and many others) are bs.
