Had my PP stage 2 243's, on for 2 weeks now, took them to my engine builder to have them checked out, everything was fine except the spring height was off, so we had to cut the spring seats down to correct the spring hieght. So other than that small hickup and the 90.00$ in machining everything is awesome. Makes real good power.
my buddy went mid 9's on patriot stg 2 243's on pump gas/meth inj last season with F1SC. Patriot gold springs are the best spring available as far as I'm concerned. I cant say enough good things about that company
Havnt had it on a Dyno yet, will post numbers eventually, im using the TRAK cam with a fast 90, and all the other good stuff and this car is now a freakin monster with the PP 243 heads.

I am aware of this, and Im not really worried about it, cleaning up the CNC tracks voided the warranty too, correcting spring height was the main concern, it was off anywhere from .010 to .030 across both heads with the exception of one cylinder which was correct. Patriot sells a good product and I have faith in them, The waranty on these heads was not a concern when I bought them. Nor was the one on the 32,000 dollar car when I bought it... All are voided...

I have the PP LS1 Stage II heads and I spray the **** out of them with my setup, and nothing bad (knock on wood) has ever happened to them. I have had those heads on for about a little under two years. And I go to the track at least 10 times in a year. I loved the performance I got from them for the price.
