what's up guys...
Here's the question:
I have an lsvtec setup right now. It has P30's and BC3's. I want to swap out the P30's for CTR's and the BC3's for BC4's. I was wondering how the Piston to valve clearance will be. I will definitely clay once I get them, but if they are known not to fit together, there's no point in me buying them. My PR3 head is milled .002 as well. My instinct tells me it won't be a problem at all, but just want to see what you're opinion is on this. I think tom run's the BC4's with over 13:1 compression w/ an LS crank/rods/block right?

I searched, but after 30 mins of searching, I couldn't fine exactly what I was looking for.

 

bump...i even tried searching for ctr's and skunk2 stg 2 cams (same lift as bc4's) but no luck...

 

Should not be a problem, if they are the same as skunk stg 2's. I KNOW those work with ctr pistons.

 

keep the p30's.. CTR's are too much compression.

 

I have complete engine management, and I am a tuner myself, so tuning is NOT an issue with compression for me. I also have a gas station that has 110 octane down the street from me...so that's not a problem.
