Do these use canted valves? Would these be not allowed in the top-stock class?

Just looking for info...

All this splayed valve talk, can i get some of your seeds to plan a money tree?

A canted valve head is considered an "unconventional head" so that will eliminate you from A LOT of classes.

I was told my 18* head was not considered an unconventional head by TSDR here.

Thats the information I was looking for. Are the 18* bowtie heads not allowed in TS class? My question is really that simple.

If you can answer this question, please let me know. Otherwise, go plant your own money tree!

You'll will have to greatly reduce the valve size that comes in most of those heads to get them to fit on stock block. If its even possible, most are setup for a 4.125 or 4.155 bore.

In which racing series?

If you're talking about Nats classes, what you have already will take the class, based one what usually shows up to race.

Frank - our trucks are going to be going around and around until I can afford to put some real money into a decent set of heads and I turn the boost up to 30# like you run... Until then - you're fine!

Me? Chicken out? Estas loco chico!

I don't know when Frank and I will be lined up next to each other (did we even do that at Nats 11?), but it should be fun either way! I might try the track one more time in a few weeks to make another pass....let the temps get down a little more before I go again...
