JDubz84 said:He already has that setup but has roush heads with 2.02 valves and 1.6's. The pistons are Hyperutectic with dual valve reliefs, so yes, the pistons are already going to be cut.
Daggar said:Yes, it's true. If you go to the Twisted Wedge website, it will tell you what the maximum recommended lift is (it's in a .pdf file on the site).
The rule of thumb for 86 flat tops is no more than 224* @ .050" dur, No less than 112* LSA,
You can go up to approximately .550" lift.
I don't know if that will differ on pistons from later year cars. The TW heads don't use the stock valve reliefs.
\JDubz84 said:My buddy plans on running this set up, but were not sure if we will have piston to valve clearance problems. Stock crank, Ford Motorsports F303 cam, Hyperutectic pistions with dual valve reliefs. He plans on switching to the Trick Flow Twisted wedge heads with 1.92 valves, and getting 1.7 rockers. I have heard that the twisted wedge heads are the only set of heads that you can get 2.02 intake valves and keep your stock bottom end. Is this true? Thanks in advance.
z2o_what said:so would it be safe to ue TW heads with stage1 cam with a stock 86 short block?
JDubz84 said:As long as the lift is not ovr .550 With a stage one cam, you should have no problems. And the Roush heads use the stock valve locations.
