He has a set of Frankenstein Stage 2 heads coming into the shop in the next week or so.The have Manley stainless valves with .660 springs installed. They are oviously more then porting my stock ones but I'm wondering if they are worth it. The have great reviews. Thanks

Hello,
Our stage 2 LS3 program is a pretty huge port. I normally like to recommend these to folks with 400ci+ or power adder applications. They use a 2.180" intake valve and a 1.600 exhaust valve. Only time I recommend these on an SBE deal is if it will turn 7500RPM+. If you have any questions about our products or service feel free to send me a DM or contact us.
