Twisted Wedge Clearances
 

I hate to do this, and bring up subjects over and over again... I DID search for this and found some posts about it... but I figured maybe different people will asnwer this one. The information tends to be inconlusive.

And here's the age old question:

With TFS Twisted Wedge heads, 1.6 FMS rockers, stock cam and the recommended push rods, will I need to do anything to my pistons.

then, if NOT, what cam can I get away with and still not worry about clearances.

i used to run trick flow's with the stock pistons, with a 520 lift cam and never had any clearance issues. i think you need to start worrying if you go with a cam above 540 lift

what are the specs of a the stock cam? 1.6 is stock rocker ratio right?

1.6 is the stock rocker ratio, and the stock cam has 210 int 210 exh. and 444lift on intake and exhaust. i believe it has 115lsa too. if you are running the stock cam, you will have NO problems at all with those heads with the stock pistons.

would it be best to go with 1.7s and the stock cam or just go with a different cam... I guess my real question is what cam can i go with before having to mess with pistons, wich I dont want to do

Get the TFS stage-1 cam and 1.6 rockers.
The cam isnt all that expensive, and probably cheaper than a set of rockers!
