243's with ms4
 
i have a set of fully cnc-ed aftermarket casting heads.. but basically a 243. (64cc, and a 2.02 intake valve.) has anyone cleared with a ms4 cam and a simpilar set up? id hate to have to sell my ms4 just to run these badass heads! plz give your oppions!

I have a custom cam that has specs very close to the MS4 and you will be fine as long as you measure though.

I'm getting closer every day to figuring out the specs on that Ed Curtis stick you run!

If there are larger valves in the heads I do not think it will clear with out some flycutting. I would definately measure if you end up putting that setup together.

Mill em down and have your pistons flycut. Then you'll have more power without a worry.

Can you measure the valve drop? That'd give us a better idea of how much room you have to play with and eliminate most of the variables!

i dont like the idea of flycuting.. whats this cam that is almost a ms4? i want a cam that pulls like a train top end but yet still has the bottom end. i hope to be getting a friends motor really soon he is dumping a 408 in his car and gonna let me have his motor as a donor. ill check with it and see if it can be ran with a somwhat close to stock size gasket.... but still interested in that cam

AZPS02 414/359 NA 501/433 100 shot through an A4 Ed Curtis cam
Ran an 11.8@118 like my sig says on 91 octane 2500 feet w/ a DA of 4165. LS1 stock bottom end. It pulls from 3K till 7K hard. If you want I can pm you my set up.

OP..... I just caught you have 2.02 intake valves so I am with Jon and don't think it will clear w/o flycutting ......
