head work?

yup can do comp. check. I really don't think it's lacking any power for what it is. I've had a few cars in my time. It's only got a few thousand miles on it, I can only launch about 1/2 throttle for the first few feet, spins a bit hitting 2nd. That's with the 17" tires, the 15" Eagle tires would just spin all the way through 1st and into second (trying to leave easy then nailing it). I'm hoping it was decked. I've never had it on the strip, just estimating the 1/4. I know amount of tire spin is a silly way to judge power, It just feels it's working well. It pings on anything less than 91 octane, I think the timing is at 34 total (couple years ago I set it). But, absolutely before tearing it down I can make sure it's healthy. got it on the traction bars LOL, wouldn't want anyone to think that. Pinion snubber is inexpensive and simple. I assume you can cruise around with one and not have it bottom out, while it can still do it's job on the launch? Any info on what my heads are from the info on my last post?
