Will These Heads Fit my 273?

It should not cost 900 to redo as stock 273 heads. Go somewhere else.

It shouldnt cost you more than $500 to recon your 273 heads, and would be the easiest and best bet for you.

Don't use the 360 heads unless you can mill them safely to 64 cc's which is where the 273 heads really measure in terms of chamber cc. When the compression isn't changes, the 360 will make more power .

Anyone who questions this needs to talk to IQ52.
