Heads, TFS, Mast, PRC, AFR, Edelbrock, other ? The main limiting factor being 4.005" bore and cathedral, and must retain normal straight rocker arrangements to suit my Jesels
Is there any real winner in terms of flow or performance for these heads on a turbo application ?
They all seem to be in the 215-245cc runner range, similar size valve ranges etc. Flow quotes really dont seem to vary that much. Max valve lift I'd use is around 630
On paper the Trickflow seem to be the flow winners by a little on the intake, but clear winners on the exhaust side.
Mast look good and seem to be cheaper, although they would require LS3 rocker setup ? And on some pictures of their, they seem to have almost no waterways on the head face ?
As per my head destruction thread, I'm in the market for new heads. My preference is another pair of Trickflows. That said, I do have an old set of Edelbrock 215's I used years ago that would work fine if I bought a new set of valves for them. On paper they do seem to flow around 10% less than the TFS225's, with less flow so on the exhaust side same as all other heads really.
The Edelbrocks would clearly be my cheapest option...although even though quoted flow is only 10% less...looking down the intake port, it really does look tiny compared to the Trickflows.
These did perform superbly for me though way back in 2006/07 before I moved to TFS heads.
With boost would the small 215's ever actually be a restriction ? 1000-1200hp range ?
What are peoples preference these days ?

SPS haymakers, they'll hold 2000 horsepower with ease. My buddie had the 255 TFS on his cat eye and they splitted right down the side from boost. He is the owner of Mafia Motorsports.

For a little background for those who maybe didnt see it in the internal section...
I will make it clear I am not in any way blaming the heads for this as the heads have served me very well for around 10 years. But I am also a little baffled as to why it did occur. It would seem HG failure has been the initiation of the disaster that followed. But really the HG should not have failed or even been under any stress worth talking about and for most part my car does generally run faultlessly.
At the minute my main line of thought is terrible meth distribution in the Holley intake, although I'm still not even convinced by that as I've never seen any other users have issue here.
