    Can anyone tell me if the stock GT valves are as good as or better than manley racemaster valves? I have a complete heads, valves springs and all. But also have 20 racemaster 1mm over 9stock gt) intake valves and 4 exhaust valves, so id need to buy 12 more, or just stay with the GT valves. looking at running 24 psi on a 9.25 to 1 motor.

    Also, any thoughts on the L&M modular spec'd pistons vs the MMR 2500R manley pistons?

    I like the L&M pistons. Ive not heard much feedback on the MMR pistons yet, but seems like they offer many different options as well

    I am going with the MMR2500R pistons custom made, just waiting for some funds to return to me, had to buy some high end parts for a job im doing. As far as valves, I have 20 intake valves and 4 exhaust valves, so 12 more exhaust and im good, BUT the GT ones do look undercut on the stems. I was told they are ferra valves.
