Looking for some new heads for my 03 z06. My last set on my gto was some AI 243s that worked great. I really want to try something else. Haven't seen much on anyone running the mast 215 heads. Seen them on Ed Curtis website. There a little bit cheaper than afr and trick flow. Anyone using these and how do you like them?

Mast heads are great. We're running a set of 235s and they run the number. For a 215 head they are probably the best you can buy.

I see slot of people runnin mast heads just want some feedback from some 215 owners. I'm in Hawaii so its a big time difference and with work difficult t times to call mast or Ed Curtis.

Where are you finding Mast heads for cheaper than AFR? I think you're mistaken.

So I heard that the mast 215 are the new etp heads like you had. Is that correct? Did you flycut?

The MAST 215s with the options I'd like... hollow-stem intake valve, dual valve springs, Ti retainers, rocker stands, and milled... comes in around $3300 for the set.

Yikes.

I'd consider AFR 215s Mamofied at that price point.

Hi Treys06gto,
You obviously didn't find the opportunity to read my thread...

And yes, that's correct.

I have the predecessor to the MAST 215 heads, the PI heads. The car drove phenominal when I was NA, but then I decided NA wasn't enough and tossed a few psi of boost on them and now it's really fun.
