Thinking of selling a few things and looking at some Trick flow Twisted Wedge 205cnc having them milled to 58cc and seeing what they flow was wondering how much power they will produce Max? I have the old style trick flow heads now with shaft rockers with just some port work and new valves and springs. 408W all forged eagle internals -22cc J&E pistons zero decked, o-ringed, main girdle, 1 3/4 headers, would be going with a solid roller cam .625 .640 285 290 106 and a super victor. Tell me what you think? Just don't have the money to do the whole R head with new headers and exhaust.Also would be getting them through T.E.A.

I am in the middle of doing about the same deal with my car. I had the original TW heads (1996 heads) that had been ported and the flow #s on the 205s were better then what I had. So I picked up a set of the 205s, the shop I got them from (Power Adder Solutions) claims they saw a 74 rwhp increase from a old TW head to these. I doubt I will see that kinda gain, but hope to pick up something. I'm taking them to a local shop here shortly to have them flowed and see how accurate those #s they publish are.

on a 408. I would for sure do 225cc Highports on a 408.

As compared to a r head? 418", 13.5:1 super victor 1000 hp carb, low 700's cam, 100-200 shot eventually. I dont have exhaust yet, starting fresh.
thanks Sam

Just worried about low compression only going to be about 10.5:1.

I run a set of TFS HP's 255cc on a 411ci and it runs strongs on motor but really runs strong on the juice! Like Sam said go 225cc or bigger as we all know we all like to go faster in the future and with that head you can grow into them still.

It is a street driven car, So they wouldn't be to much head?

Definately not on a 408. My brothers 347 has the 205's. He drives 300 miles a day with them.
