think i should flycut? i've searched this topic for a couple hours so far this morning and there's a lot of information about it but nobody with my particular setup...i need to hear from the guys that knooow this stuff, i know you're out there!
and sorry for another 'will i need to flycut' thread..
I ordered this from TSP:
PRC stage 2.5 5.3L heads milled to 59cc chambers 2.04"/1.575" Valves
(I need to call about those valves...their drop down box when ordering just heads has the only valve option as 2.02"/1.575"....??) dual spring kit, 7.4" pushrods
Torquer v.2 232/234 .595/.598 112 LSA (don't know if its advanced, sorry...i didn't give them additional instructions on the advance, so whatever it is regularly i guess..)
GM MLS gasket (.051 right?)
So you think I'll need to flycut with the milling job? The lift isn't TOO extreme, but I'm afraid its going to be close..

I would worry more about the duration. Always measure to be sure.
The valves that come with the PRC Stage 2.5 5.3's are 2.02 and 1.575.
I had to flycut with my Torquer V3 as I had little to no clearance on the intake side, that is before I switched to the 228R. We have the same heads, only I am running a .040 Cometic.
Also, even though you already have pushrods, measure for the correct length. I am sure TSP will hook you up if you need to swap them out.

edit: NEVERMIND i see your sig haha
Since I'm running the thicker gasket, do you think I'll be alright?
What pushrods did you use?
Thanks

I am gonna default and say to measure to be sure, its the right thing to do. I used the Comp Magnum pushrods. I got them for $99.00 from Va. Speed. My measured PR length came to 7.350 with preload.

I had to go with 7.5 pushrods on my 59cc heads. Just get some modeling clay and check clearance, and get a pushrod checker while you are at it to make sure they are right. It is only 20 bucks or so.
