Does anyone know what the max lift on the 94 GT40 iron heads(not P) are? I have a TFS stage one cam and plan on using the stock 1.7 roller rockers on the heads but can't find any info on what the stock springs can handle.
Max lift possible with stock springs?

ive heard up to about .540. im at about .529. you will be at .544 on the exhaust with 1.7's so if i were you i would upgrade them or use 1.6's.
Well that makes me feel a little better. I was told they are only good to .520 lift max. This way I can toss on my stamped stock 1.6's untill I get new springs. Thanks for the info!
