Save your money and buy USA Made Heads!!!!
Pro Comps are junk.
Have bad installed valve guides,some have stripped stud threads, some are 20
to 30'' of being straight,some come cracked, and many other problems with
cheap labor.
I sold Pro Comps for 3 months out of 74 sets I've sold after 2-8 months
39 sets had minor to major issues. 23 sets were unrepairable or too expensive
too even attempt to fix.
JMO Save your money buy AFR,Brodix,RHS,Dart heads. 8)

Only a rich man can afford to buy junk because he has plenty more to dig himself out if all else fails.

Have you looked at water/alcohol injection? Reduces detonation potential.

Was a fad a few years ago and its back again. I see it in JEGS.

You can use windshield washer fluid.

It is $300 approx for the kit.
