I just bought a pair off this heads and i was told that im going to have to notched the pistons on my car so they can fit,I have a 1991 gt with a ford racing short block,the one that comes with hyper pistons and a explorer cam,any help will do i also wanted to upgrade my cam,whats the biggest cam i can get

Since they're the 2.02 valves, you'd be advised to notch the pistons. You can do it yourself, get an Isky Racing Cams piston notching tool and you can do it with the engine in the car.

Cam choice depends on what you want out of the car. Is it a daily driver? Will it be smog checked? What intake and fuel system do you have? What tranny and rear end gears do you have?

where can i get that isky tool?and no the car is not going to be smog tested,not a daily driver but i will drive it on the streets,These are my mods so far, 410 gears,moiser 28 spline axles,detroit loker,upper lower contol arm,50/50back,90/10 front,aluminum drive shaft,subframe connectors

Click on that link, and look on the left side and click on Tools & Kits. Then page down one time and you'll see Notching Cutters.

About the cam, I'd go with this one.

Comp Cams Magnum 35-312-8, grind number 276HR. It has .544/.560 lift, 276/280 duration, 220/224 duration at .050 lift, a 114 degree LCA and a powerband of 2000-6000. It needs a 5 speed or a 2500 stall speed converter if used with an automatic, and everything else it needs you already have.

i have the performer rpms on my 93 302 block with a tfs stage 1 cam that, i just installed last week w/o any ptv issues w/ the 202 valves so you might want to clay the heads first b4 buying that tool.

 

[rdrgwll6]

how is youre stang running after you put the heads on,any good diffrence in power

 

[alexcor]

yes it made a good difference, exhaust sounds crispy too, for the price i think is a great head next to the TFS T/W heads. I dont know what the biggest cam you could get would be but remember to clay the cylinder to make sure your ok.
