Trick Flow GenX 220 Cylinder Heads
I'm just after some info and peoples opinion's on the Trick Flow GenX 220 heads
Has anyone used these on a standard stroke LS1? Can they be CNC machined?
Looking at running them with a 230ish cam with 600 lift
Sorry for the open ended questions
Cheers

For the $$$ they are the best head out there IMO. If you want to CNC them you you have to run them out to the TFS 235cc program and put in bigger valves so it is not a LS1 head anymore.
I'll let you in on a little secret....They have the exact same port as the cnc'ed 215's.The 215's are really 219cc so the 220's are only one cc bigger. Ron at Vengeance made a post saying they were about 7-10 less than the cnc'ed castings.
I run a touched up set on my motor......

So the cast heads only lost 7-10 hp as opposed to the cnc'ed ones?
The long term plans are for a PD blower down the track, will these heads provide a suitable platform to support FI? The cam I'm looking at should support FI

have some 220's miled to 59cc's going on right now at LMR along with a 226/230 cam. I'll post the dyno results monday or tuesday... but you really can't go wrong with them in any form. The 215's (cnc version, and no doubt a better flowing head of course) only add about 10-15 more hp at moat though, so the 220's are really a GREAT bang for the buck if our trying to budget at all.

Dont know if cam specs helps but looking at this range 23x 23x @600lift with 113-115 lsa
Is it better to spend the extra and get cnc'ed heads as it will be more of a benefit with FI?

Sorry mate, I dont understand what I will see less of a difference in
I realise cam choice is very important and the cam will be selected with FI in mind. FI is a little further down the track for the time being so I want to have a H/C for the time being

a blower needs a different cam profile to make best power.it needs more exhaust duration and a wider lsa.make a 2 piece timing chain cover if you plan to swap a NA cam to a FI cam.

The cam is going to be FI friendly. Will the heads be FI friendly?
The 2 piece timing cover is a good idea but
Was thinking about having the heads shaved down to 11.1 compression and then when I go the blower run it on E85

I know that, looking at running 10 psi anyway. People are running 10psi with 10.6-1 with the Harrop PD blower kits without problems
