For GTP Stage 2 heads with TR224 cam, what pushrod length would I need? 7.350 or 7.400 <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> Thanks in advance.

I bought them from Thunder Racing. How can I find out how much they have been milled? Don't all GTP heads come milled at .30 thous? Thanks.

Our GTP heads are milled .030. Because the base circle of the cam is a little smaller then stock we still recommend 7.400 pushrods with that set-up. You could use the 7.350 without a problem but it will reduce lifter preload causing the valvetrian to be a little louder. Hope this helps...

 

Thanks for the help guys. Will I have to shim up the rockers, though?
