gt40p heads from ebay


It's the stock 91 H.O. from a mustang. Stock roller cam. I intend to get a cam too (E303), should I wait on the springs and rockers till I have the cam?

The springs will work well with either cam. Going with a 1.7 rocker arm and an E303 should be OK. But it's getting almost to where you want to check PTV clearance. I am actually leaning towards the E303 as well, and I have 93 Cobra rockers (1.71's).
 
I see. Is there a rocker I could use now that would work with the e303 when it comes into play?? Like a 1.6x? Could always get taller valve covers right if anything?

The 1.6 is the factory ratio. So you won't gain any lift off of that. You may gain a tiny bit going to a roller rocker though.
 
It's a 5/16" thread, and you will need pedestal mount though - not stud mount.
 
That's what I read. And when I looked for pedestal mount I couldn't find the stud size so I figured it was different. Just wanted to confirm. Got any for sale?

I only have a set of stamped rockers... sorry.
