I've never stated the CV-1 heads are the best thing out, I hate getting lumped into the cheer leading. I actually tried to get Tigers and they were out of stock, so I bought 1- CV head and a pair of KRE HP's. I was a skeptic based on the lack of performance, but I wanted to draw my own conclusions.

For the record based on FACTS.

My new 68 Firebird had a 525ci Tiger Race engine in it when it was built. Best ET was around 9.26 @ 146. Weight on the car was around 3150lbs. This is not a slam on the guy who owned the car before me, Tiger heads or previous engine builder. Our 511 CV-1 went faster to the 1/8 on the SECOND PASS having fuel system issues. The weights are virtually the same, same gear, same trans, same 8 year old tires. So when someone continues to question if the heads can make as much or more as other Pontiac heads, I call BS because I have first hand experience. People want to see ET slips, I have one.

Best of luck with whatever you decide.

All of us aren't high rollers like some 😉. Financially it was going to be a stretch just to get to Norwalk, new car, truck and trailer. Knowing we didn't get any runs on the car before the race, we could learn a few things and maybe have some fun, tires were down on the list. Heck, it was someone else's engine, borrowed a battery and slept at the track to keep costs down. As Liljack once said, "it takes a village full of idiots to build a CV-1 car! Anyway I'm glad we thrashed to make it, when and if this combo starts making the power you are, I will call it a great cylinder head.

For safety reasons i would have changed them. At the speeds you hope/plan to run please change them before you run again.
