It will be very close. You will need to verify piston to valve.

I also am also worried about clearance on the tfs 215's. Mine are milled to 61 cc with a .40 cometic gasket. I have the 7.5' pushrods and 1.7 rockers, will this setup work without any problems? cam is 233/234/604 lsa

With that much cam it will be very close.....close to tagging your pistons that is....LOL

You would be lucky to have .030 on the intake side....flycutting, aftermarket pistons, or a different cam should be in your future.

62cc. 61cc or smaller you may have to flycut.
