I placed an order for some AFR 195 part number 1040, but then I see that there is a part number for 1041s for a 72* intake center bolt angle...for engines newer than 87'. Do I need to cancel and get the 1041s? I'm not keeping the TPI. My car is a 91'.

 

Elongate center intake holes if 90 to 72

 

Hsr ? Has both patterns
as for the vc pattern can get for perimeter or center bolt or they offer both patterns on the head for a additional price.

 

Yeah luckily that HSR I picked up has both. Just wanted to make sure, I was lucky to find a pair of AFRs from Jegs that were in stock, otherwise everybody is 3-4 weeks out. They had the 7/16" rocker studs too.

Any head bolt recommendations....7/16" for SBC right? ARP looks like they have a nice set, I was going to go with the Scorpion non self adjusting rockers and some perimeter valve covers. What valve covers look good, fit well, and are reasonable? Last time I bought a pair of AFR Valve Covers the perimeter bolt pattern didn't match the AFR heads and I had to dremel out the holes to fit.

 

I think afr site lists recommendations on arp bolt part numbers.
