the etp giii heads came as low as 38cc but I cant find a website or phone number for them?

is there anyone else who makes 3x-4x cc heads already done?

People seem to be a bit fan of angle milling and getting down to the 50cc range
That would also involve fly cutting in stock shortblock scenario,no? .i would like to preserve the integrity of the piston amap

Surely someone makes small chamber heads

C5R head that I know of.

IIRC you can get the Mozez, LSR from Edelbrock and I'm sure Bob has a small chamber program.

Kinda overkill for a stock short block.

Smallest chamber I know of is the PRC 62cc chambers in their As Cast heads. IIRC they also offer that chamber on their 227 and 237 heads.

That would be the most feasible for what you're doing.

I know angle milling doesn't effect ptv as much as flat milling. But if you were rolling over a set of trick flows or something that already had increased valve clearance I would think you could probably get away with a lot.

AI has some small chamber stuff in stock casting if I remember right.

TEA will do a set of Trick Flows with the combustion moved away from the spring seat, making the chamber smaller. My 245s came with a 62cc chamber. Seems like they could get it down in the 50s if you wanted.

Why not get a set and just cut them.
My mean street motor has stock 243 castings @ 43.5cc's
Woah. How much of a cut?
